I need to simulate transient pressure waves in water. With other software, I've done this using a linear dynamic analysis, intended for solid materials, but set the shear modulus of the material an order of magnitude below the young's modulus in order to approximate the behavior of water (i.e. make the shear waves insignificant compared to the longitudinal waves).
Doing this implies a poisson ratio >> 0.5. Mecway internal solver will not let me do this, nor will CCX.
I understand that poisson > 0.5 does not make sense for a solid analysis. But it actually does make sense (I think) for modelling linear pressure disturbances within a bounded volume of liquid-like material.
Any ideas how to achieve my objective?
Thanks!
Marc

Watch your boundary conditions carefully, and be sure your mesh density will resolve the spatial wave behavior you are trying to resolve.
