Hi, Luc, yes, I am using my own script for uniaxial tests (a simple one). Vaclav recommended me somehow to use uniaxialstrainer, but I still use mein. I know, I have to try the uniaxailstrainer. That is why I did not compare.
I do not use friction forces for facets, so I do not think it is a big difference between facets or spheres driving. I have attached the screenshot from tension simulation. As I described earlier, the specimen divided into 2 parts with different mask.
