Hi,

I am trying to model a simple freefall of an iron block over an iron platform in COMSOL Multiphysics.

I have added the gravity property under the Solid mechanics module. But when the block strikes the platform below, it bounces with a greater force defying the law of energy conservation. How can i make the collision inelastic as it appears in a real scenario?

I have attached the project file, any comments would be helpful.

Thanks
