Although not normally used in this manner, the following commands also allow tabular loading: BFA, BFK, BFL, BFV, DA, DK, DL, FK, SFA, and SFL. See the *DIM command for more information on defining your labels. The VELOCITY label refers to the magnitude of the velocity degrees of freedom or the computed fluid velocity in FLUID116 elements. In addition, some real constants for elements SURF151, SURF152, and FLUID116 can have associated primary variables.

Defining Independent Variables 2.5.14. Applying Loads Using TABLE Type Array Parameters If you need to specify a variable other than one of the primary variables listed, you can do so by defining an independent parameter. To specify an independent parameter, you define an additional table for the independent parameter. That table must have the same name as the independent parameter, and can be a function of either a primary variable or another independent parameter. You can define as many independent parameters as necessary, but all independent parameters must relate to a primary variable. For example, consider a convection coefficient (HF) that varies as a function of rotational speed (RPM) and temperature (TEMP). The primary variable in this case is TEMP. The independent parameter is RPM, which Release 13.0 - © SAS IP, Inc. All rights reserved. - Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates. 51
