Problem with a Box Geometry drill through a TriMesh Geometry

I have an ogre entity ,then, I cerate a triMesh geometry for it.When another entity is falling down with box geometry ,the box drill through the triMesh.
Any idea why this is happening?
I guess there maybe something wrong with the boxmass,but I dont know how to set the boxmass properly?

what do you mean by drill? show the debug objects and check for any obvious mistakes, compare your properties to those in the simple scenes demo.

try to up de density, i had the same problem.
