1 Introduction

What is WinDrift WinDrift is the Windows 95/98/Me Pre and Post Processor for the seakeeping computer code NEWDRIFT. The computer code NEWDRIFT is a 3D panel program enabling the calculation of the hydrodynamic responses (6 DOF motions and wave induced loads, including drift forces) of arbitrarily shaped bodies (including nonzero forward speed ships and floating structures) in sinusoidal and irregular seaways. The original NEWDRIFT code was developed by Prof. A. D. Papanikolaou in the years 1983-1987 and was since then continuously updated by him and his research team at the Ship Design Laboratory of National Technical University of Athens to allow for the consideration of more practical applications [1-5]. The Windows version of NEWDRIFT, namely WinDrift was developed within the scope of the EU funded project SHEAKS (BRPR-CT97-0605).



2 Setup and installation

This section describes the installation of WinDrift in your PC- MS Windows system. Information about setting the environment variables and configuring your system for WinDrift is also provided. 2.1 Hardware Requirements WinDrift is designed for Pentium PC- MS Windows systems. It does not pose special constraints for the hardware requirement beyond those imposed by the Windows 98 operating system. 2.2 Software Requirements To successfully run WinDrift you have Windows 98/Me installed in your computer. Furthermore in order to use the disposed geometry visualisation tools you should also have AutoCAD R14 or higher installed in your system [6]. CIMNE’s GiD Pre and post processing system for F.E.M. calculations is also supported and its installation can significantly facilitate the preparation of the geometry-input file [7]. Results’ diagrams/charts are visualized with MS Excel 2000. 2.3 Files and Directories Used by WinDrift When you install WinDrift, the necessary programs and data files are copied by default to “Program Files\WinDrift2000\” directory. The user may define through the installation process another directory. Under this, two (2) additional directories are created. Namely “\Spectra” and “\Samples”. The second one has four subdirectories containing tutorial files for Geometry, Old version input, New version input and Load calculations. 2.4 Installing WinDrift in your system. To install WinDrift software takes the following steps:

1. Insert the diskette labelled Disk 1 into drive A:\. 2. From the taskbar menu select Start > Run. Select A:\Setup.exe 3. Follow the instructions in order to insert the rest of the installation diskettes and

copy all files to your system. 4. Follow the prompt by the installation program and restart your computer. 5. Run again the A:\Setup.exe program. 6. Select the directory you want to install WinDrift if other than the default. 7. After the installation has finished quit the installation program.

2.5 Setting Your Display Mode WinDrift is designed for SVGA mode 1024x768 resolution with “Large Fonts”. Display Settings other than those defined herein might create minor problems to the designed forms.



2.6 Windows 95/98/Me System Settings WinDrift requires that Windows Decimal Symbol is set to “.” and the List Separator to “;”. This can be set through the Taskbar menu following the sequence:

Start > Settings > Control Panel > Regional Settings > Number where the above settings are in the first and the last text box of the form. Note: In case this procedure does not solve the problem at your computer, you should change your Regional Settings to one containing by default the above setting requirements, for example “English (UK)”.



3 General information about WinDrift

3.1 How to Run the Program WinDrift ’s installation will create a directory in your hard disk for its files/directories and will insert a New Program Group in your Windows Taskbar. The first contains the executable files while the second contains all the link required for running the application from the Windows environment. In order to run the program select with your mouse pointer in sequence:

Start > Programs > WinDrift 2000 > WinDrift 2000

WinDrift will respond with the Login Form. Fill in the username and password provided by SDL-NTUA. Please make sure that your hardware lock has been attached to an Parallel port (LPT) otherwise an error message will inform you that your hard-key is missing. In such a case, please fit the hardware lock to your computer and follow the same procedure again. After passing this initial level of processing a form containing a brief description of the program will appear at your screen. It will stay for few seconds and then disappear giving place to the main WinDrift ’s Graphics User Interface (GUI). 3.2 Screen Layout

Figure 1. WinDrift Window



WinDrift’s 2.0.1 layout is shown in the figure 1. The screen is divided into three main regions: - Program banner where WinDrift’s name is displayed. - Menu bar that is located exactly below the program banner and displays the

names of the menus that you can use in the active window. - Toolbar with buttons that perform few of the most important program functions. - The fill-in form (that is the largest area on the screen) containing text and other

control boxes, ready for the insertion of the program input data. - The status bar that is the last line at the bottom of the screen. 3.3 Entering Data All the required data for the execution of the kernel application, namely NEWDRIFT, are displayed in the fill-in form. This latest version of WinDrift, namely release 2.0.1, has a simplified input form considering the needs of a ‘normal’ user: it excludes redundant information and assigns default values according to the developers’ experience and the interaction with the end users. Also, all integer switches used in the previous version have been replaced by corresponding text equivalents. Thus the user does not have to consult the manual in order to select the appropriate value. The transition from one text box to the other can be accomplished by using the Tab key or the mouse. In case the user inserts by mistake erroneous data (e.g. non-numeric value in a numeric text box) the program does not proceed, requiring the user to correct its data. The program also supports copy and paste features of data values between the various text boxes. 3.4 Exiting WinDrift The user can exit the program using the # button at the top right corner of the form or using the Exit command from the File sub-menu.



4 Geometric viewing operations

An essential part of the input file is the definition of the geometry. WinDrift supports three different import formats:

$%Data eXchange File format (.DXF) $%GiD’s Mesh file format (.MSH) $%NEWDRIFT Geometry definition file format (.DFG)

For the former two file formats the reader should refer to AUTODESKS AUTOCAD User’s Manual and to CIMNE GiD’s User’s Manual respectively. As for the additional *.DFG format, this contains the definition of the nodes and elements used for the description of the ship model. This format corresponds to the geometry definition section of the application NEWDRIFT input file. Thus, the first line contains the number of nodes and elements followed by definition of the Id and coordinates of the nodes and the Id and the nodes that delimit it (see, NEWDRIFT Manual). WinDrift does not provide own viewing and modelling components. However, using its Import modules, WinDrift can use 3D geometry models created and checked by AUTOCAD and GiD. The user can also view an existing geometry input file using the View Geometry by AutoCAD R14 button or by converting the .DFG file to .MSH format from the “Convert files between NEWDRIFT and GiD” command of the geometry sub-menu, and then import this file into GiD.



5 Using WinDrift – Preparing an Input File

The first action, required by the user, is to have the geometry description of the object to be examined readily available. If the user intends to perform motions calculations, with viscous damping included, and/or calculations of wave induced sectional loads, then it is very important that the description of nodes is given section by section in a direction from the stern (aft) to the bow (forward). This is also a requirement for the definition of the corresponding panel elements. Furthermore, when forming (defining) an element, the nodes are circumvented so that a right hand rule normal vector, applied to an element, is always showing to the fluid domain. Given the geometry definition, the user may start building the rest of the input file. Starting with the title; the symmetry properties and the general body particulars (length; breadth; draft; etc) and finally the integral mass characteristics (centre of gravity, radii of gyration); it then follows the insertion of the geometry file. WinDrift will recognize the number of nodes and elements, for which input has been provided and calculates the body’s displacement (without herein taking into account symmetries). The next step is the selection of the various additional options provided by NEWDRIFT, such as the consideration of viscous damping effects; the selection of fluid and body points, for which motion calculations are desired and the selection of sections, for which wave-induced loads should be examined. WinDrift R. 2.0.1 has now the ability to recognize automatically the longitudinal sections, that the user has defined in the course of the nodal input: the user has now only to select how many of these (viscous, mass or load) sections should be included in the calculations using a user-friendly window. The third stage of the input procedure concerns the selection of various methodological, calculatory parameters. Thus, he will decide about the way of use of Green’s function; the inclusion of forward speed or shallow water effects. Also, at this section, he may define the output file options, such as the extent of the output details and the rewinding or not of the output file, after each calculation. The final step of the input procedure is the definition of the exciting waves’ headings and wave periods, for which the calculations should be performed. WinDrift R.2.0.1 supports the latest version of NEWDRIFT, for which, in a single run per speed case, a series of wave headings and periods can be considered. More details regarding the preparation of the input file are given in the Tutorial (7.1). 6 Using WinDrift – Execution and Post processing

6.1 WinDrift/NEWDRIFT Execution With the completion of the above procedure the input file will be ready for execution. The user may now save the input file for later use or define this as the actual input file

Figure 2. Element Definition.



for the execution. In both cases a prompt will ask for the new file’s name and storage location. After the input file for execution has been defined, the NEWDRIFT execution button will be released and the user may start running the application. There are two different modes of execution: - the external one, where NEWDRIFT will be executed in a Windows DOS shell and - the internal one, where NEWDRIFT will be executed within WinDrift. The former one is recommended for longer runs. NEWDRIFT creates automatically the following files: $% Input. $% Output. $% Outnew.

$% Specres. $% InXYZ $% Plot1

$% Pressures $% Relwave

6.2 Output Postprocessing The processing of the results has two main parts. In the first one charts of the motions responses and loads, included in the output file, are properly prepared for further processing by the Microsoft Excel Program. This makes the postprocessing more versatile and easier adjustable to the needs of the users’ reports. 6.2.1 Response Amplitude Operator Diagrams WinDrift prepares charts of Response Amplitude Operators (RAO ’s) from the Spectral Analysis submenu, using the Draw RAO Chart command. The user is prompted to select an *.SPI (SPectrum Input) file. This is essentially a specres format file such as shown in figure 3. The user may use one or more earlier produced RAO output files by separating each group of results from the next one with the placement of –1. in the first column. The user will be prompted to give the respective spectral data. The results can be accessed by an ASCII editor (such as Notepad) or in the form of an Excel Workbook with the respective charts prepared. For the handling of the charts and relevant worksheets the reader should refer to the Microsoft Excel manuals.



6.2.2 Load Responses WinDrift R.2.0.1 considers the preparation of charts for the load responses, similar to those prepared for the motion spectra. This utility is accessed through the Sectional Loads RAOs, in the Advanced Tools submenu (figure 4). The user is prompted to select a relevant output file and if this contains the sectional load calculations, the relevant data are automatically located and a Workbook in Microsoft Excel is prepared. If there are no data available for the sectional loads, an error message will appear and the program will return to the main screen. 6.3 Spectral Analysis An important WinDrift ’s utility is the spectral analysis tool. This gives to the user the capability to calculate the ship response spectral characteristics in irregular seas. The sea spectra supported are: The BRETSCHNEIDER spectrum formula (also known as the ITTC two parameter spectrum) is commonly used for open ocean conditions (deep water, far away from land). The JONSWAP spectrum, which is considered more appropriate in coastal waters (limited fetch, shallow water). A User defined (discrete) spectrum. The program provides the user the ability to define his own spectrum and find the responses of the ship to it. The format of these data is:

Figure 3. SPectra Input (.spi) file format



(2F10.5). For each pair of input data, the first number is the frequency and the second one is the respective wave spectral density. WinDrift using the above sea spectra calculates the response spectral characteristics, such as spectral moments; statistical significant and extreme values; mean zero-crossing periods; mean periods of peaks etc. It provides the user with all necessary information to assess the ship’s performance in the given natural sea conditions. Details regarding the output post processing and the spectral analysis are given in the Tutorial (7.2-7.4).



7 Tutorial

In this section the steps required to run a WinDrift example (evaluation of the seakeeping of a bulkcarrier) are described. 7.1 Input file preparation & Execution 1. Starting the Program Start WinDrift from your Windows Taskbar. 2. Load a Bulkcarrier input file

From the File drop-down menu choose Open. A standard Windows dialog box will appear on your screen. Navigate through your directories in order to find the directory where you have installed WinDrift. If the default settings have been used then it should be under your C:\Program Files\ directory. Go to the Samples/New Input Format/Bulkcarrier subdirectory and choose Bulkcarrier.inp file.

3. Sections selection

WinDrift will open the input file and it will notify you about the number of longitudinal sections, it has detected, in case you choose to include viscous effects or perform sectional load calculations. Click OK and a form with all the sections will appear at your screen. In case you do not intend to perform any of the above calculations, just click Cancel button. Otherwise you may select the section you would like to be included in your input file by double-clicking in the relevant column next to the section. Please remember that geometrical sections must be continuous and that mass sections are a subset of viscous sections and load sections a subset of mass sections.

4. Check the input form

When the above procedure has been finished, the user will revert to the main window. Now all the text boxes will be filled and the selected options checked. The user may check the number of nodes and elements, inserted through the input file, as well as the displacement (in m3) of the input geometry. The text box next to the Insert Geometry data command button will be empty because it is used only when an external geometry definition file is inserted.

5. Click Input File

Note that the Run Drift button is not yet enabled. You should first have to write the input to a new file (for safety). Therefore click Make Input. The Save dialog box will help you find the location you prefer to store the data while WinDrift will make a last check on their validity.

6. Run Drift

Now the ‘Run Drift’ Button will be enabled and the execution may start. A message box will inform you that you may run Drift in a DOS shell or under WinDrift’s control. The former one (DOS shell) is recommended for long runs. Click Yes and a window will appear, where all NEWDRIFT messages will appear.



7.2 Drawing RAO Charts 1. Starting the Program

Start WinDrift from your Windows Taskbar. 2. Loading an spectrum input file

From the Spectra analysis drop-down menu choose Draw RAO Chart. 3. Select Spectra.spi sample file

Appendix A – Differences between New and Old Input format

In the course of the SHEAKS (BRPR-CT97-0605) project, the SDL-NTUA team has made several changes in the NEWDRIFT input file in order to simplify the common user’s input requirements and to reduce the user’s load during the input preparation. In the course of this update of the NEWDRIFT input file, the ship definition data have been moved to the forward part of the input file, whereas the calculatory case data are now given at the end of the input file. Furthermore, the capability of performing multiple heading and wave period calculations in a single run (per ship’s speed) has been incorporated.
