Metallic glasses behavior in compression

I am trying to simulate compression tests using Comsol. The feature of material, which I would like to compress is that this material has many shear bands (10 nm in thickness) or nm- sized gaps. Is it possible to build this model in Comsol? To simulate compression, I need these inhomogenities (gaps, shear bands) to be interacted with each others. Will these gaps to propagate or to nucleate during simulation of compression ?
Also when I am doing compression with for example 20-30 small gaps, resolving is going well but when there are a lot of gaps for example more 100 - 1000 any errors is appearing (although geometry of sample recognizes in Comsol quite well (but not always))
Also error is appear with the meshing of gaps, if they has large difference in size). How to mesh in other way, or what do I need to avoid in geometry of my sample for avoiding mesh problem?
Best Regards,
Oleksii
