Resultant force on an object.

Please login with a confirmed email address before reporting spam

Hy,
I am a student mechanical engeneering trying to learn the basics of the comsol CFD module.


I am facing the following problem:
When trying to determine the resultant force (+- drag) acting on a sphere immersed in a fluid (such as water) I seem to be unable to determine its value.

This is how I proceed:
I set up a volume an then I put the sphere inside the volume. I then applied a mesh to the volume and defined the boundary condition (inlet: uniform speed; outlet: 0Pa).

Can someone explain this force?
