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.

EN – Defines an element by its number and node connectivity. If you need to do that yourself because you want to apply a load or boundary condition in a certain direction besides the global Cartesian, use NROTATE. EDRD – Switches a part from deformable to rigid or from rigid to deformable in an explicit dynamic analysis. NANG – Rotates a nodal coordinate system by direction cosines.
MOVE – Calculates and moves a node to an intersection. PROD – Multiplies variables.
VSBW – Subtracts intersection of the working plane from volumes divides volumes. AATT – Associates element attributes with the selected, unmeshed areas. CBMX – Specifies preintegrated cross-section stiffness for composite beam sections.

PDEF – Interpolates an item onto a path. It works a lot like the D and F commands. The official explanation is: DVAL – Defines values at enforced motion base. VEXT – Generates additional volumes by extruding areas.
ESLN – Selects those elements attached to the selected nodes. The F command is the same commanx the D command, except it defines forces instead of displacement.
KSEL – Selects a subset of keypoints or hard points. So the entry for creating a node looks like this:. NLOG – Forms the natural log of a variable. Nonrestrictive Data Input 1. RSYS – Activates a coordinate system for printout or display of element and nodal results. PSMAT – Writes an assembled global matrix to a adl format that graphically displays nonzero matrix values.
Therefore, instead of defining a Node in your model as: KSLN – Selects those keypoints associated with the selected nodes. Table of Contents 1. LSBV – Subtracts volumes from lines. VSLA – Selects those volumes containing the selected areas. L Commands L – Defines a line between two keypoints. But based on the support calls we get and the scripts we write, this 20 are the most common that we use. MAP – Maps pressures from source points to target surface elements. SSPA – Specifies a preintegrated membrane stiffness for shell sections.
SAVE – Saves all current database information. HFANG – Defines or displays spatial angles of a spherical radiation surface for sound radiation parameter calculations. NSLE – Selects those nodes attached to the selected elements. GRPH for improved performance with plotters. EMF – Calculates the electromotive force emfor voltage drop along anshs predefined path.
CYL4 – Creates a circular area or cylindrical clmmand anywhere on the working plane.
Sometimes you may want to write out specific information, say list the stresses for all the currently selected nodes, to a file.
VA – Generates a volume bounded by existing areas.

DATA – Reads data records from a file into a variable. AFSURF – Generates surface elements overlaid on the surface of existing solid elements and assigns the extra node as the closest fluid element node.
TREF – Defines the reference temperature for thermal strain calculations. L2TAN – Generates a line tangent to two lines. CNTR – Redirects contact pair output quantities to a text file.
