[CIG-SHORT] Make two independent rough surfaces contact each other

[Ekaterina Bolotskaya]

Dear Pylith developers,

I have a 2D simulation of a rough fracture. It consists of 2 separate surfaces (upper and lower), one edge of which has a rough profile (bottom edge of the upper surface and upper edge of the lower surface). The rough edges are not initially in contact.
I would like to load the upper and the lower sides of the model to bring the asperities in contact with each other and look at plastic deformation.

When I'm trying to do it Pylith moves both parts towards each other as if they are allowed to overlap (no contact, no deformation at the asperities).
Is there a way to let it know the two surfaces are supposed to contact each other.

Thanks!
