Results comparison between Nastran and Optistruct in Dynamic simulation

Recommended Posts

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!

If you have latest version of HyperWorks 2019, then please check the OptiStruct online help for verification problems.

This manual presents solved verification models including NAFEMS problems.

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!
