Hallo Everyone,

 

how can man define a Force 100 N in 10 Substep in Optistructur, that means, every Substep just apply 10N.

 

We know, we can define a load in ansys for a Force, for example, NSUBST,10

 

But how define man in optistrutur

 

thx!

    Hi FalcoW,

     

    In NLSTAT (Quasi static analysis)>> NLPARM card>> make NINC to 10.

     

    For more information on Quasi static analysis, please refer to OptiStruct help.

    Hi,

     

    Try this:

     

    Have two load cases. one with pretension and the second with force

     

    For pretension have NLPARM with NINC=1 and for the second have NINC=10.
