Static Loadcase Combination

Static Loadcase Combination

Create combined loadcases from a Nastran OP2 file using linear superposition.

Loadcase Name

Specify a name for the combined loadcase.

Select Subcases

Select the subcases to combine

Set Factors

Factors can be applied to the selected subcases (Default = 1.0)

Create Combined Loadcase

Press Apply to create the combined loadcase

Read/Write Combinations

To save time having to create different loadcase combinations each time a new D3PLOT session is started, the combinations can be saved to a text file. The combinations can then be read back into D3PLOT in later sessions.

The file is a simple text file and could be generated by an external program as part of an automatic process. The format is:

START_SUBCASE,<name>

START_SUBCASE,<name>
<subcase_id>, <factor>
<subcase_id>, <factor>
<subcase_id>, <factor>
.
.
etc.
END_SUBCASE
START_SUBCASE,<name>
<subcase_id>, <factor>
<subcase_id>, <factor>
<subcase_id>, <factor>
.
.
etc.
END_SUBCASE
.
.
etc.

The file is not model specific so you could save combinations from one model and read them in for another. If a selected subcase ID doesn't exist in the new model it is ignored.
