Transient Analysis

Altair Forum User

To evaluate the response of a structure submitted to a periodic sine wave force in the time domain, can I define the OptiStruct loadstep as 'transient direct'? Does 'transient direct' and 'transient modal' differ in computational cost only?

Hi @Ariane Rebelato

 

Yes you can run a transient analysis.

 

Direct method is slightly time and computational expensive over modal transient.
