So, as a way to get ANSYS Mechanical users out there started down the road of loving APDL commands, we got together and came up with a. Directly type in the commands into a text file from scratch. This assumes a good knowledge of the ANSYS command language and the associated options.

Data required for the calculation of the element matrices and load vectors, but which cannot be determined by other means, are input as real constants. You must log in to post a comment.

BSTE – Specifies a thermal expansion coefficient for a nonlinear general beam section. EDCTS – Specifies mass scaling and scale factor of computed time step for an explicit dynamics analysis.

ANSYS Commands Topic Index

BF – Defines a nodal body force load. FJ – Specify forces or moments on the components of the relative motion of a joint element. My own professional opinion is that FEA without command file input is only marginally more practical than tits on a tomcat.

For many older users this is not a problem because we grew up using the text commands. If you need to go into another processor you can, you simply issue the proper command to change processors. If you change the active coordinate system make sure you set it back to the global system with CSYS,0.


CSYS – Activates a previously defined coordinate system. It is a truly parametric comand language in that you can replace most values in commands with parameters.

TIME – Sets the time for a load step. PPATH – Defines a path by picking or defining nodes, or locations on the currently active working plane, or by entering specific coordinate locations.

20 APDL Commands Every ANSYS Mechanical User Should Know

The simplest example are material properties. IRLF – Specifies that inertia relief calculations are to be performed. Sometimes you may want to write out specific information, say list the stresses for all the currently selected nodes, to a file.

EDRI – Commmand inertia properties for a new rigid body that is created when a deformable part is switched to rigid in an explicit dynamic analysis. NCNV – Sets the key to terminate an analysis. MP – Defines a linear material property as a constant or a function of temperature.

Mechanical APDL Command Reference

BFK – Defines a body force load at a keypoint. KSUM – Calculates and prints geometry statistics of the selected keypoints. F The F command is the same as the D command, except it defines forces instead of displacement. ANIM – Displays animated graphics data for linear problems.


SSPD – Specifies a preintegrated bending stiffness for shell sections. If you issue an NSEL and get say the nodes on the top of your part that you want to apply a load to.

DSYS – Activates a display coordinate system for geometry listings and plots. D Commands D – Defines degree-of-freedom constraints at nodes.

TIMP – Improves the quality of tetrahedral elements apld are not associated with a volume. LINA – Finds the intersection of a line with an area.

ANSYS Command File Creation and Execution

A Commands A – Defines an area by connecting keypoints. We will focus on actual commands you use to do things in the program here. NCNV – Sets the key to terminate an analysis. EDPL – Plots a time dependent load curve in an explicit dynamic analysis.

RACE – Defines a “racetrack” current source.

FORM – Specifies the format of the file dump. EMID – Adds or removes midside nodes. ASBW – Subtracts the intersection of the working plane from cpmmand divides areas.
