Simulating movement

Please login with a confirmed email address before reporting spam

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
