[CIG-SHORT] Initial stress interaction with Dirichlet bc

[Ekaterina Yevgenyevna Bolotskaya]

Dear Developers,

I'm currently working on a 2D simulation where I need to initially compress a 2D block in both directions and then fix both displacements of lower horizontal boundary and apply a horizontal displacement rate on the upper horizontal boundary.
The problem is that my initial compression interacts with my Dirichlet bc: I have the whole block compressed but the horizontal boundaries themselves (I'm talking about time 0, when there's no rate yet). I get smth like this:

[cid:3b2c73aa-e832-440b-a2ad-5c02567767df]


While I want to compress the whole block uniformly and only after have the compressed block fixed.
Could you tell me if I can do that and how?

Thanks!
