Loading MBD forces into FEM

Hi everyone, 

 

I'm seeking for help in a topic which I'm fairly new to. I have a complete running MBD model of an automotive vehicle complete with different loadcases.

The model provides forces on all joints and pre-defined points. 

The question I have is;

 

1. Is there a way to automatically load the output forces on a joint, into a static FEM-analysis?

 

And some follow-up questions if this is to be true;

 

2. Can I pre-define the time at which the most relevant forces occur?

3. Can this be automated as well? For example: At a given time x, the combination of forces in 3 joints give the highest combined loadcase, but it is not necessary to be the highest force in one of the joints. This could occur at time x2.

 

This would greatly increase our evaluation process of a frame.

 

Thank you in advance!

    Hi Tom,

     

    Right now there is no way to automatically load the extracted loads from MV in HM OptiStruct/Nastran.

     

    Please get in touch with your local Altair Support team from which you can ger guidance in writing a scirpt or routine for the same.

    Well, Actually you can try InspireMotion... A new module in Inspire combined with multi body simulation

     

    You can download 2017.3 Inspire with Motion Feature in license to use it.
