EN – Defines an element by its number and node connectivity. JSOL – Specifies result items to be stored for the joint element.

ANSYS Command File Creation and Execution

VDDAM – Specifies the velocity spectrum computation constants for the analysis of shock resistance of shipboard structures. EDPL – Plots a time dependent load curve in an explicit dynamic analysis. CBTE – Specifies a rdference expansion coefficient for a rference beam section. Most people use nodal selection or components to apply displacements to multiple nodes. CS – Defines a local coordinate system by three node locations. LSBV – Subtracts volumes from lines. The F command is the same as the D command, ansya it defines forces instead of displacement.

AINV – Finds the intersection of an area with a volume. PRED – Activates a predictor in a nonlinear analysis. An exclamation point is a comment in APDL. FILE – Specifies the data file where results are to be found.

The more complex the element you are using, the more the number of values you can store.

CS – Defines a local coordinate system by three node locations. TYPE – Sets the element type attribute pointer. BFK – Defines a body force load at a keypoint.


DA – Defines degree-of-freedom constraints on areas. Any characters to the right of one are ignored by the program. FILL – Generates a line of nodes between two existing nodes.

IRLF – Specifies that inertia relief refrrence are to be performed. Conventions Used in This Reference 1. MOPT – Specifies meshing options.

F Commands F – Specifies force loads at nodes. We will focus on actual commands you use to do things in the program here. In fact, I was in a room next to one of our support engineers while they were showing a customer how to change the elements that the solver would solve Mechanical defaults to the most common formulation, but you can change them to whatever still makes sense and the user had to admit he had never really used or even seen APDL commands before.

This is the fastest way to change an elements definition. V Commands V – Defines a volume through keypoints.

LSTR – Defines a straight line irrespective of the active coordinate system. LDIV – Divides a single line into two or more lines. Log in to Reply.

Mechanical APDL Command Reference

TCHG – Converts node degenerate tetrahedral elements to their node non-degenerate counterparts. The layout is explained in the help: ELBOW – Specifies degrees of freedom to be coupled for end release and applies section asnys to elbow elements. DIG – Digitizes nodes to a surface.

KBC – Specifies ramped or stepped loading within a load step. CBMD – Specifies preintegrated section mass matrix for composite-beam sections. But you can specify multiple nodes, multiple degrees of freedom, and more powerfully, the value for deflection can be a table. FTYPE – Specifies the file type and pressure type for the subsequent import of source points and pressures. VSLA – Selects those volumes containing the selected areas.


RDEC – Defines the decimation parameters.

See what happens when you execute them. LINL – Finds the common intersection of lines. NSYM – Generates a reflected set of nodes. VPUT – Moves an array parameter vector into a variable.

KSLL – Selects those keypoints contained in the selected lines. PPATH – Defines a path by picking or defining nodes, or locations on the currently active working plane, or by entering specific coordinate locations. L2TAN – Generates a line tangent to two lines.

Condensed Data Input 1. Instead arguments for commands are separated by commas. EDIS – Specifies stress initialization in an explicit dynamic full restart analysis.

PLZZ – Plots the interference diagram from a cyclic modal analysis. SFL – Specifies surface loads on lines of an area. SSPE – Specifies a preintegrated transverse shear stiffness for shell sections. LSLK – Selects those lines containing the selected keypoints.

ESEL – Selects a subset of elements. NKPT – Defines a node at an existing keypoint location.
