Simulating movement

Hi,
I'm trying to simulate the movement of a certain body when it is subjected to wind forces.
Is there any easy way to do this in Comsol.
Thank you
Viddy

Hi
there are two ways: either you know the pressure field spatially and temporally (or in frequency content) and you apply this as a boundary pressure load to your Solid (structure physics),
Or you go for a full FSI (fluid-structure interface) physics which is far heavier but gives a coupled interaction: the wind pushes the structure that changes the wind shape etc.
But a more complex model means more time to set it up, to run it, and to validate it, not to say larger computer(s), you might need a cluster depending on your model size

Good luck
