There are a few ways how to simulate a wall, depending on purpose and other
circumstances:
- using wall [1]
- using facets [2]
- using "connected spheres" using some cohesive material, like CohFirctMat
- something else [3]


> And how to fix one end of the rebar to the wall?


depends on your wall modeling technique, for example using spheres, the fix
could be done by a common sphere belonging to both rebar and wall..

yes, see e.g. [4], where Law2_ScGeom_CpmPhys_Cpm
and Law2_ScGeom_FrictPhys_CundallStrack are used together.
