secfunction

Mapdl.secfunction(table='', kcn='', **kwargs)

Specifies shell section thickness as a tabular function.

APDL Command: SECFUNCTION

Parameters
  • table – Table name or array parameter reference for specifying thickness.

  • kcn – Local coordinate system reference number or array interpretation pattern for this tabular function evaluation.

Notes

The SECFUNCTION command is associated with the section most recently defined via the SECTYPE command.

A table (TABLE) can define tabular thickness as a function of coordinates. Alternatively, you can use an array parameter (indexed by node number) that expresses the function to be mapped. (For example, func (17) should be the desired shell thickness at node 17.) To specify a table, enclose the table or array name in percent signs (%) (SECFUNCTION,%tablename%). Use the *DIM command to define a table.

The table or array defines the total shell thickness at any point in space. In multilayered sections, the total thickness and each layer thickness are scaled accordingly.

The Function Tool is a convenient way to define your thickness tables. For more information, see Using the Function Tool in the Basic Analysis Guide.

If you do not specify a local coordinate system (KCN), the program interprets TABLE in global XYZ coordinates. (For information about local coordinate systems, see the LOCAL command documentation.)

When KCN = NODE, the program interprets TABLE as an array parameter (indexed by node number) that expresses the function to be mapped.

When KCN = NOD2, the program interprets TABLE as a 2-D array parameter (where columns contain node numbers and rows contain the corresponding thicknesses) that expresses the function to be mapped.
