Hello everyone, i am doing linear static + modal analysis to be to AcuSolve for fsi simulation.

Optistruct simulation details:  riser pinned at two end (constrain at xyz translation, free xyx rotation) + upward force (top tension) define as load. The loadsteps in optistruct are:

 

1. Linear static:

    spc: defined
    load: defined

 

2. modal Analysis:
    spc: defined

    method (struct): defined

    statsub (preload): linear static

 

I get an error during importing op2 file into acuconsole-eigenmode manager; 'internal error: inconsistent number of eigenvalue.

The error only occur when there are two subcase (linear static + modal analysis).  If i only do modal analysis without linear static, i can import the op2 file without any error.

 

Is there any way(s) i can exclude linear analysis in 'output: op2 card'?

 

Attached is the thread in AcuSolve forum with sim files.

 

 Thanks in advance!
