Hi,

I'm, thinking about modeling stress in solids generated by an ultrasonic source, but after doing some tutorials there are still some basic questions:

1) is it even possible to apply an acoustic load using the linear elasticity solver, or do I have to couple it with the Helmholtz(?)-solver?
2) and if I have to do so, are there any additional examples for the Helmholtz-solver (beside the one in the tutorial)?

I've recognized that there is only a little resonance on acoustics questions here, but I hope that you can help me anyway.

Thanks...
