2.4. APDL Commands These commands make up the ANSYS Parametric Design Language (APDL). The commands are grouped by functionality.

Table 2.18  Parameter Definition

These APDL commands are used to define parameters and their values.

*AFUN Specifies units for angular functions in parameter expressions.

*ASK Prompts the user to input a parameter value.

*DEL Deletes a parameter (GUI).

*DIM Defines an array parameter and its dimensions.

*GET Retrieves a value and stores it as a user-named parameter.

/INQUIRE Returns system information to a parameter.

PARRES Reads parameters from a file.

PARSAV Writes parameters to a file.

*SET Assigns values to user-named parameters.

*STATUS Lists the current parameters and abbreviations.

*TAXIS Defines table index numbers.

*TREAD Reads data from an external file into a table array parameter.

*VFILL Fills an array parameter.

*VGET Retrieves values into an array parameter.

*VREAD Reads data and produces an array parameter vector or matrix.

Table 2.19  Macro Files

These APDL commands are used to build and execute command macros.

*CFCLOS Closes the "command" file.

*CFOPEN Opens a "command" file.

*CFWRITE Writes an ANSYS command (or similar string) to a "command" file.

*CREATE Opens (creates) a macro file.

/DFLAB Changes degree of freedom labels for user custom elements.

*END Closes a macro file.

/MAIL Mails file to specifed address.

/MKDIR Creates a directory.

*MSG Writes an output message via the ANSYS message subroutine.

/PMACRO Specifies that macro contents be written to the session log file.

/PSEARCH Specifies a directory to be searched for "unknown command" macro files.

/RMDIR Removes (deletes) a directory.

/TEE Writes a list of commands to a specified file at the same time that the commands are being executed.

*ULIB Identifies a macro library file.

*USE Executes a macro file.

Table 2.20  Abbreviations

These APDL commands can be used to define abbreviations for longer commands, and to create user-defined commands.

*ABBR Defines an abbreviation.

ABBRES Reads abbreviations from a coded file.

ABBSAV Writes the current abbreviation set to a coded file.

/UCMD Assigns a user-defined command name.

Table 2.21  Array Parameters

These APDL commands are used to operate on parameter arrays (i.e., vectors and matrices).

/DIRECTORY Put the file names in the current directory into a string parameter array.

*MFOURI Calculates the coefficients for, or evaluates, a Fourier series.

*MFUN Copies or transposes an array parameter matrix.

*MOPER Performs matrix operations on array parameter matrices.

*MWRITE Writes a matrix to a file in a formatted sequence.

*SREAD Reads a file into a string array parameter.

*TOPER Operates on table parameters.

*VABS Applies the absolute value function to array parameters.

*VCOL Specifies the number of columns in matrix operations.

*VCUM Allows array parameter results to add to existing results.

*VEDIT Allows numerical array parameters to be graphically edited.

*VFACT Applies a scale factor to array parameters.

*VFUN Performs a function on a single array parameter.

*VITRP Forms an array parameter by interpolation of a table.

*VLEN Specifies the number of rows to be used in array parameter operations.

*VMASK Specifies an array parameter as a masking vector.

*VOPER Operates on two array parameters.

*VPLOT Graphs columns (vectors) of array parameters.

*VPUT Restores array parameter values into the ANSYS database.

*VSCFUN Determines properties of an array parameter.

*VSTAT Lists the current specifications for the array parameters.

*VWRITE Writes data to a file in a formatted sequence.

Table 2.22  Process Controls

These APDL commands can be used to control the order in which other commands are

processed.

*CYCLE Bypasses commands within a do-loop.

*DO Defines the beginning of a do-loop.

*ELSE Separates the final if-then-else block.

*ELSEIF Separates an intermediate if-then-else block.

*ENDDO Ends a do-loop and starts the looping action.

*ENDIF Ends an if-then-else.

*EXIT Exits a do-loop.

*GO Causes a specified line on the input file to be read next.

*IF Conditionally causes commands to be read.

*REPEAT Repeats the previous command.

*RETURN Returns input stream to a higher level.

/WAIT Introduces a delay before reading the next command.
