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. ANSYS Mechanical APDL Command Reference – Ebook download as PDF File . pdf), Text File .txt) or read book online. ansys apdl.

LPTN – Partitions lines. VSWEEP – Fills an existing unmeshed volume with elements by sweeping the mesh from an adjacent area through the volume. The arguments are explained in the Command Reference in the help.

GEOM – Defines the geometry specifications for the radiation matrix calculation. GRPH for improved performance with plotters. AATT – Associates element attributes with the selected, unmeshed areas. LSLA – Selects those lines contained in the selected areas.

Mechanical APDL Command Reference

GSUM – Calculates and prints geometry items. MOVE – Calculates and moves a node to an intersection. LSBA – Subtracts areas from lines.

Command help is your friend here. ASLV – Selects those areas contained in the selected volumes. LSBW – Subtracts the intersection of the working plane from lines divides lines. F The F command is the same as the D command, except it defines forces instead of displacement.


20 APDL Commands Every ANSYS Mechanical User Should Know

FL – Defines a set of fatigue location parameters. BSTE – Specifies a thermal expansion coefficient for a nonlinear general beam section.

SOLU – Specifies solution summary data per substep to be stored. BFE – Defines an element body force load. ESLV – Ansyw elements associated with the selected volumes. VDOT – Forms an element table item from the dot product of two vectors. SSLN – Selects and displays small lines in the model. PSEL – Selects a path or paths.

NSLK – Selects those nodes associated with the selected keypoints. EDIS – Specifies stress initialization in an explicit dynamic full restart analysis. CYL5 – Creates a circular area or cylindrical volume by end points.

But you can specify multiple nodes, multiple degrees of freedom, and more powerfully, the value for deflection can be a table. SSMT – Specifies preintegrated membrane thermal effects for shell sections. Right now you need these commands. ANIM – Displays animated graphics data for linear problems. One thing to be very aware of is that each node in a model has a rotation associated with it.

SUPL – Plot result data on all selected surfaces or on a specified surface. LSLA – Selects those lines contained in the selected areas. ESLN – Selects those elements attached to the selected nodes. CBMX – Specifies preintegrated cross-section stiffness for composite beam sections.

ANSYS Commands Manual Topic Index

EXP – Forms the exponential of a variable. It appears that the rigid body runs straight through the composite part constraints definedand the simulation takes forever having to terminate manually.


EMID – Adds or removes midside nodes. SADD – Forms an element table item by adding two existing items. ESEL – Selects a subset of elements. LFSURF – Generates surface elements overlaid on the edge of existing solid elements and assigns the extra node as the closest fluid element node. Above we point out that all entities have an ID. BF – Defines a nodal body force load. TREF – Defines the reference temperature for thermal strain calculations.

GEOM – Defines the geometry specifications for the radiation matrix calculation. 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.

BFA – Defines a body force load on an area. NGEN – Generates additional nodes from a pattern of nodes.

SRSS – Specifies the square ansyss of sum of squares mode combination method. ESYM – Generates elements from a pattern by a symmetry reflection. ASUM – Calculates and prints geometry statistics of the selected areas. EDBX – Creates a box shaped volume to be used in a contact definition for explicit dynamics.
