Workflow Lubby 2 creep example

Hi everyone,

i want to remodel the Lubby 2 creep example in the small defarmations section. I started by drawing the geometry in Gmsh and meshing it after assigning the physical groups. I exported a .msh file (v2 ASCII) and converted it to a .vtu file using the tool GMSH2OGS. After that i reordered the nodes using the tool NodeReordering. Now i have some .vtu files.
Can someone explain to me what are the next steps?
How should i assign the material parameters and the shear force on my model?
What are the steps needed to be done and in what tools?

Thank you in advance
