Selecting a Load Case

If more than one load case or substep exists, the user might intend to choose the load case that is to be taken into consideration. Also, for modal analysis where more than one eigenfrequency is calculated, a selection of the eigenfrequencies of interest is required.

The specification of a load case/ substep or a mode is done using the definition of the related analysis type, the load case number and the substep (if applicable).

This task shows you how to:

Select a Load Case in Tosca Structure.gui

  1. Choose Command > DRESP.
  2. Add a LC_SET as shown in the following figure:

    If more than one FE input file is used, then the numbering of load cases is not necessarily unique because the numbering of load cases might start with 1 in each input file. For avoiding this problem, the GUI offers the possibility to select the name of the file that contains the load case to be used in the design response definition. The load cases in the first referenced file in the FEM_INPUT command then get their original numbers (for more information, see About Loading FE Data in the GUI and FEM_INPUT). If there is a second file referenced in the FEM_INPUT command, then 10,000 is added to its load case numbers; for example, load case 11 in the second file is referenced as load case 10011. If a third file is referenced, 20,000 is added to its load case numbers, etc.
