DMIGModel Reduction for multiple structures

prasad.guduguntla.external

Hello,
I need to perform a assembly run with reduced models and a residual model.
The reduced models are in dmigpch format.
In each reduced model - SUBCASE ID's 2 & 3 (with loads) are used during the model reduction.
 
In the assembly run, I created 2Subcases for each reduced model.
But in the f06 file, Output(for example OLOAD resultant) is generated for SUBCASE 2 and 3 only, other subcases shows 0 values.
Now for a assembly run, how to define the subcase for each reduced structure(2 subcases for each reduced model).​ So that I can define SUBCOM's for each reduced model.
 
Thanks,
Prasad.

    Hi,
     
    Attached is a sample example and depending on the load combination you are trying to achieve expanded case control structure could get complex. Load sequence should be properly defined. It may be best to contact msc helpdesk at mscnastran.support@mscsoftware.com with detailed explanation of of your situation.

    Expanded Case Control section of the SUPERLEMENT USER'S GUIDE would also provide additional details.
