request specific subcase in .op2 format

Nazrin

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!

Hi,

 

Instead of requesting global output results, you could request op2 format only for loadstep 2. In the model browser ckick in the loadstep2 and under outputs select the desired output and choose op2.

Hi /profile/97129-adriano-a-koga/?do=hovercard' data-mentionid='97129' href='<___base_url___>/profile/97129-adriano-a-koga/' rel=''>@Adriano A. Koga,

You mean this section right?:

<?xml version="1.0" encoding="UTF-8"?>

 

This is where i lost. In the global output card .op2 i dont have to select specific output. Only output >  op2 > frequency > options. Even after i check loadcase 2 > output> .... ,  i still cant find out options for op2. can you help with visual aids? Your help is very much appreciated.

Correct. In the browser you're highlighting, you can enable only for tour loadstep of interest: output>>displacement, format op2.

Delete any other output/global output cards.

Thank you very much! it works!

Hi, i am doing linear static + modal analysis to be to AcuSolve for fsi simulation too. Can you give me your optistruc file. My email is 103170038@sv1.dut.udn.vn or vantaoc4@gmail.com. Thank you.
