Mechanical APDL Basic Analysis Guide

Cartesian, spherical and cylindrical coordinate systems are valid). If working in batch mode, you need
to define the table before issuing any of the loading commands.

For more information on defining table arra y parameters (both interactively and via command), see
TABLE Type Array Parameters of the ANSYS Parametric Design Language Guide.

2.5.15.1. Defining Primary Variables

When you define the table arra y parameter, you can define various primary variables, depending on
the type of analysis you are doing.Table 2.10: Boundary Condition Type and Corresponding Primary
Variable (p. 51) lists boundary conditions and their associated primary variables for supported types of
analyses. Additional primary variables are available using function boundary conditions. See Using the
Function Editor (p. 80) for more information. Primary variables are shown as the valid labels used by
the DIM command. You can apply tabular loads according to a local coordinate system defined via
LOCAL, and specified in DIM.

When defining the tables, the primary variables must be in ascending order in the table indices (as in
any table array).
