Hello all,

I am currently working on NVH Frequency response analysis with optistruct and nastran solvers and I see an error of opproximately 10%. Same FEA model has been used in both solvers and the error is 10%. If both the models are created in their corresponding solvers, then the error comes out to be 7%. How good is Optistruct solver for NVH to match Nasran solver? Any benchmarking done on this? Please help me out.

 

Thanks and regards,

Punith
