Wind - Mesh against solid object

Hi Everyone.

Sorry if this sound a bit dull as a question.

I'm working with wind force to simulate the behaviour of a mesh wrapped around a sphere.

How can I set the closed Brep to be perceived as solid abject and avoid the flying mesh to fly through it? I've tried Collide surface but it hasn't worked. Please help if you can.

Hi Fabio.

CollideSurface and CollideMesh only check for collisions between points and the surface/mesh.

As you show, this can mean that a mesh between the moving points can sometimes penetrate the volume slightly. Things can be improved by using a denser mesh for the moving part, or using a small offset of the volume you want to be solid as the collision volume.
