OptiStruct – REPCASE command


Topic description: The REPCASE command can be used to indicate the start of a repeated subcase definition. This is used for multiple output requests of the same type for the same subcase.

 

General Overview

OptiStruct allows only one set of result output for each subcase. When you want results from multiple sets (disp, elems) etc., you can bypass this with REPCASE card, which allows multiple output requests on repeats of subcases.

  • Each REPCASE must be declared with a separate REPCASE header and a unique RID.
  • The REPCASE identification numbers should always be greater than the preceding subcase that is being duplicated (and all previous subcases).
  • REPCASE definitions should immediately follow the subcase that is duplicated.
  • REPCASE is currently supported only for Linear Static Analysis.

 

Example

An example of REPCASE card usage is displayed below.
