Chrono: two balls collison problems
When I used Chrono to simulate the motion and interaction between two balls sedimenting in viscous fluid, In some special cases I found two balls merge into one ball when sedimenting(I changed CFL but it didn't always work). I wonder how to fix it?
Another problem I met is I could't sucessfully simulate the trajectory of a spinning sphere entering into water. Its trajectory was still symmetry, resembling non-spinning sphere.
