Hi Everyone,

I am having difficulties running my models in abaqus. I think it is due to some mass scaling issues as I have large differences in mechanical properties between different parts of my model. Can someone help me out with some insight/documentation that can explain numerical issues that are associated with large differences in material stiffness's in FE.

Thanks guys
