Assessing noise level during impact (explicit with acoustics – possible?)

      Hi,


       


      I have an explicit simulation (impact test of a device) and I am looking for a way to assess the noise levels during impact (compare to test results and do a comparative analysis study between different designs).


      Is it possible to do such a thing using ansys with the results from an explicit simulation?


       


       


      Thanks.

      The frequency domain acoustic BEM solver or transient acoustic FEM solver(*MAT_ACOUSTIC) can be coupled with explicit analysis to do impact noise simulation in LS-DYNA.

      So only possible with LS-DYNA? not with the explicit-str module (autodyn)?

      Yes, the frequency domain acoustic BEM solver is available only in LS-DYNA.
