Hi All,

 

I'm trying to set 2 load cases (static) using include files. The aim is to apply 2  loads on the same object (or a part)  in two different positions.

 

The scheme is as follow:

I can create include files, one for each position, I can't manage these files for each load case.

Is there a manual for this or can you explain how to do it?

 

thank you

    You should make 2 LC in 2 master files

    If SPCs and mesh are same, we make 2 LC in 1 file to take advancetage of same stiffness matrix inversion

    Ok, It's clear, so, in other words, it 's impossible to change stiffness matrix in a single run , specially in linear static.

    The only way is to create a bach file on windows to run consecutively two 'master'. Do you know the command line, for Optistruct, to start a sequential run and not a parallel? (I knew for Nastran there were two different command for sequential and parallel run execution)

    Yes,

    Once you have 2 master *.fem files, just select them as 'Input file(s)' on Hyperworks Solver Run Manager , optistruct will queue them (sequential run)
