Results comparison between Nastran and Optistruct in Dynamic simulation

Dear all,

In my company, we are using Nastran and Patran to do frequency response simulation and random response simulation, but I see that Optistruct could do the same,

did any one have a comparison between the two software?  I mean whether the response stress/acc/dis is same in a more complex situation.

Looking forward to your answers.

Thanks!

    Thanks Rahul, I will take a look on this!

    Meanwhile, I am modeling a FR simulation in Optistruct, then I will compare with the old results!
