Eigenfrequency study with FSI interface in 4.3a

Please login with a confirmed email address before reporting spam

I attempted to use the FSI interface with the eigenfrequency study step using its default configuration under 'custom studies' in the model wizard. The study step indicates a warning, however, so I suspect the eigenfrequency solver settings are not compatible with the physics settings. I included a simple model to illustrate the fault. All eigenfrequency solutions appears at 'NaN.'

Has anyone had any luck with this interface using an eigenfrequency study?

Hi

no way, it's not set up for those equations. Eigenfrequency and fluics is tricky and does not work as easly as for solid alone.

Good luck
