cloth simulation

[lemonriver]

I used a triangular mesh to construct a unclosed static rigid body, and used softbodyhelper to construct a cloth.
I found that the cloth will penetrate the static mesh easily under the force driven by mouse.Meanwhile a closed soft box
will not penetrate the static mesh. Any one knows the reason?
Another issue, the cloth created by softbodyhelper is always too softy. how can I make it harder ? Some paper say that
an big damping coefficient will make sense. However it make cloth looks strange
Hope for help

I try to reduce the step size of internal clock. It works at the cost of slowing down.

Instead of decreasing the simulation step size, try increasing the "piterations" (position solver iterations) for the softbody simulation to make it more stable.
