01.Preprocessing
1. Enhanced Framework
The latestest framework of GTS V200 provides a more intuitive and versatile working
environment. Especially, Task Pane enables the user to customize the menus for his favorite
tasks. It maximizes the operational efficiency of the user. Since the user can arrange the menus
by his own work flow for each analysis type, it helps the user generate anlaysis models with
much less time and effort. In addition, by locating all favorite functions in a single window, the
user invokes a desired menu swiftly without searching through the menu system. It eliminated
the disadvantage of working in a Windows-based GUI.
GTS consists of various analysis types such as Linear/Nonlinear Static, Construction Stage,
Slope Stability, Seepage, Eigenvalue, Seismic Response Spectrum, Time History, and
Consolidation. For each analysis type, analysis conditions (i.e. loads and boundaries) are
defined differently. As such the user should apply them with good understanding of applications
and experience in numerical analysis. In the previous versions of midas GTS, the user guided
himselves through complex analysis procedures with their own knowledge. However, with the
provision of all the necessary features in a specific analysis in the Task Pane, the user can follow
the menus in a step by step workflow. In addition, GTS enables the user to customize his own
favorite analysis procedures. It provides the following 3 major aspects of functionality.

3. Division of 3D Elements
A 3D mesh often needs to be refined for detailed analysis results. In GTS V200, a function for
dividing 3D elements has been added for the users convenience. This function is useful whengenerating a Hexa Mesh, which ensures the accuracy of the analysis results. The description
and the usage of the function are as follows:
Functionality
Discretize 3D elements depending on the methods.
Usage
Select Model < Element < Divide 3D.
Select elements to be divided. Select a method of dividing elements. Divide by Pattern divides elements by selecting
a division pattern and a reference point. Divide by Number divides elements by
selecting an axis and entering the number of divisions in the selected axis.
Click on Apply and confirm that the selected elements are divided.

4. Improvement in Protrude Mesh
Protrude Mesh creates 1D, 2D and 3D elements by protruding nodes, edges, 1D elements
and 2D elements. In the older versions, 3D elements could not be created directly from other 3Delements. In order to create 3D elements by protruding other 3D elements, 2D elements had to
be extracted from the Faces of the 3D elements and then the 2D elements were protruded into
new 3D elements. In GTS V200, for the users convenience, this function has been improved so
that 3D elements can be directly created by extruding, revolving, sweeping, projecting or
offsetting Faces of other 3D elements. As an example, Extrude Mesh will be presented.
Functionality
Using Faces of 3D elements, new 3D elements can be extruded into a desired direction.
Extrusion Direction can be selected among the axes (X, Y and Z) of the basic
coordinate sytem or directly defined by a 2-Point Vector. If Offset Components (Dx, Dy,Dz) is selected, the extrusion lengths in the x, y and z directions can be specified.
Enter the extrusion length in the Offset entry field and enter the number of elements to
be created in the Number of Times entry field.
Usage
Select Mesh > Protrude Mesh > Extrude.
Select EFace->3D tab.
Select Face(s) of 3D elements.
Select the Extrusion Direction method and specify Offset and Number of Times.
Define material properties for the 3D elements to be extruded, from Attribute.
Click on Preview and confirm that the Mesh is generated correctly.

drags. In order to move the model by a constant distance, press arrow keys while pressing the
Shift key, which is a newly added function.
Ctrl + Arrow keys: Rotate
Using Ctrl+Drag while right-clicking, the Work Window is rotated. In GTS V200, a new
function has been added so that the Work Window can be rotated by a defined angle pressing
the arrow keys while pressing the Ctrl key.
+/- keys on the number keyboard: Zoom-in/out
Using Mouse Wheel, the Work Window is zoomed in/out. Using Mouse Wheel, the Work
Window can be zoomed in/out as much as the mouse drags. With a newly added function, the
Work Window can be magnified or shrunk at a constant ratio by pressing +/- keys on the
number keyboard.

02.Material models
1. Modified Mohr-Coulomb Model
The Modified Mohr-Coulomb model is an advanced Mohr-Coulomb model with a hardening
cap and is suitable for any type of soils (stiff or soft). It is particularly suitable for granular
materials such as silts and sand.
The Modified Mohr-Coulomb model can account for the following material behaviours that are
characteristic of soils:
- Stiff unloading-reloading stiffness, Eur, compared to primary loading stiffnesses.
- Effect of overconsolidation on stiffness change in compression loading.
- Stress dependency of the unloading-reloading stiffness according to a power law.
- Cohesion-frictional shear failure according to Mohr-Coulombs law.
- Strain dependency of the tangential stiffness in primary shear loading (in triaxial test)
according to a hyperbolic law (Duncan & Chang model).
- Evolution of the apparent dilatancy angle (from contractant to dilatant) in primary shear
loading according to Rowes rule.
- Stress dependency of the tangential stiffness in primary compression loading (in
oedometer test) according to an exponential law.
This constitutive behaviour is achieved by combining a non-linear elastic model with two
plastic models which display independent hardening behaviours (i.e. Double Hardening model).
The unloading-reloading behaviour is described by non-linear elasticity with the elastic bulk
modulus varying according to a power-law:
with ptthe pressure shift due to cohesion:
and Krefthe unloading-reloading bulk modulus at reference pressure pref
The unloading-reloading Poissons ratio remains constant.
The shear behaviour is described by a smooth Mohr-Coulomb plastic surface, Fig. 1 and Fig 2.
Shear hardening is achieved by the variation of the friction angle from its initial value, 0, to itsultimate value, u. The strain dependent evolution of the friction angle is specified to match theDuncan Changs parabolic law at the reference pressure:
with 1the vertical strain, q the deviatoric stress and qathe assymptotique shear stress.

The flow rule for shear hardening is non-associated. The adopted plastic potential is of
Drucker-Prager type and is controlled by a dilatancy angle depending on the current friction
angle according to Rowes rule:
with cvthe friction angle at zero dilatation
The primary loading compression behaviour is described by an elliptic plastic cap with its
center at the apex of the Mohr-Coulomb surface, Fig.1:
with pcthe preconsolidation stressand a shape ratio set to a default value of 2/9
The initial preconsolidation stress, pc ini, is computed based on the initial stresses and on the
specified values of K0and Knc.
Compression hardening is achieved by the variation of the preconsolidation stress according
to the following exponential law:
with e0the initial void ratio, vpis the volumetric plastic strain and is the hardening coefficientdeduced from the oedometer modulus.
The cap flow rule is associated.

The diagram for the relative shear force per length as function of relative longitudionaldisplacement between pile and soil is defined at the Reference Depth. If the Slope of Friction-Rel.
Disp curve is not actived or assigned with value 0, this diagram will apply to every point of the
pile. However, when the Slope of Friction-Rel. Disp curve is activated, the diagram will become a
function of depth because the vertical axis of the diagram will be corrected by the defined slope.
Normal Stiffness of the interface is always equal to nK .
Parameter Description
Ultimate Shear force Ultimate shear force per length (Force/Length)Shear Stiffness Modulus ( )tK Linear elastic penalty stiffness of the interface
in the longitudional direction of the pile. If this
option is chosen a tri-linear diagram is defined
for the relative shear-force per length as
function of relative longitudional displacement
between pile and soil. This diagram is defined
by the ultimate shear force value (1st and 3
rd
line-segment) and the shear stiffness modulus
(2nd
line segment), (Force/Length*Length)
Function Multi-linear diagram can be specified for the
relative shear force per length as function of
relative longitudional displacement between
pile and soil. The veritical axis of the diagram
is dimension-less and will be multiplied by the
specified ultimate shear force value. The
horizontal axis is of dimension Length.
Normal Stiffness Modulus (Kn) Linear elastic penalty stiffness of the interface
in the directions normal to the pile.

An example model generated using Pile elements is illustrated below. 5 layers constitute soils.
A pier is on the soil and the lower part of the pier is composed of Pile elements. The soil and the
structure retain their own self-weights and no external load is applied.
Tractions and relative displacements of Pile elements are produced with respect to the local
coordinate system. The displacements of the Pile elements and peripheral soils and the axial
tractions of the Pile elements are displayed below. It is observed that the Pile elements greatly
affect the soils on the periphery and the distribution of friction at the Pile elements and peripheral
soils.

04.Analysis
1. Restart Function
While running the construction stage analysis, the user may stop at a mid-stage for a check, or
it can be terminated due to system instability or by an accident. Depending on the analysis type
and the number of analyzing stages, the analysis may require a very long time. If it has stopped
due to unexpected termination, the user must spend wasteful time to run the analysis again
from the first stage. In GTS, the restart function enables the user to continue from where it has
last stopped It will reduce the total analysis time when faced with unexpected errors during the
analysis.
Introduction
After the construction stage analysis is terminated, the function enables the user to start
again from the last saved analysis.
Usage
The restart option is specified from Analysis Case (Main Menu: Analysis > Analysis
case). After selecting Construction State as an analysis type, click Analysis Control to
invoke the Analysis Control dialog..
It provides 3 options to control the Restart function.
Save only user specified stages : It saves only specified stage by the user. If not converged save its previous stage : It saves only the last converged stage.
Save all stages : It saves all stages.

2. Drain Function
In order to show the characteristic of a drainage material, midas GTS provides Draining
Condition in this version. The Drain Condition is applied in areas where the excess pore waterpressure equals to zero, and it can be effectively used with the consolidation analysis and the
ground water flow analysis provided by midas GTS. In consolidation analysis, nodes with the
drain condition will have the pore water pressure of zero; the active pore water pressure
becomes zero to allow drainage in the ground water flow analysis.
3. Well

2. Elements Result Calculated at Nodes using Probe Result
Probe Result enables us to display nodal or element results using tags. Since some analysis
results such as stress and strain are only computed at elements, their result display using ProbeResult has been limited to element based output. In this new version, it is possible to display the
element result values on a node. It automatically calculates average of all results of attached
elements to the target node. The function is only available when Nodal Average is checked in
Status Switch of Post Command Toolbar.
3. Absolute Maximum Display using Probe Result
In addition to Max and Min display capability, the absolute maximum value checking function
has been added to Probe Result.

4. Nodal Average per Group
Nodal average is used to display contour result. This method calculates average value at a
node from pertaining elements. In the previous versions, the value was computed from all
elements around the node. However, in GTS v200, users can designate groups of averagingelements based on Mesh Set, Property or Material.
Group Type
Same Mesh Set : It calculates average only within elements of the same Mesh Set.
Same Properties : It calculates average only within elements of the same Property.
Same Materials : It calculates average only within elements of the same Material.
Usage
