Multiple materials in same geometry (from GMSH) #16247
-
I am trying to assign to different material properties to named blocks (using the Tensor Mechanics module). I have no trouble defining the two different blocks in GMSH, but if I do not add "coherence" in GMSH, then the two blocks are not joined together in MOOSE. When I do add "coherence" then MOOSE gives this error: "I don't believe that we can specify multiple subdomain or boundary ids for a given geometric entity" What is the correct way to give sub-sections of the same mesh different material properties? |

I thought I would try going about this another way, by removing the "coherence" (union) in GMSH the two geometric entities are separate, I thought that I could then apply an EqualValueEmbeddedConstraint on the displacements, but the input processor now states that it cannot add a constraint for that variable, since it is not a nonlinear variable. What is the correct way to perfectly bond multiple materials together in MOOSE (as in a composite, for example)? |

Well I guess I was just using the wrong constraint, I think I have what I was looking for using an EqualValueBoundaryConstraint, but I'm curious how this is different from a TiedValueConstraint in this case. |

I guess you should use Fragments to combine and eliminate any overlapped between two bodies. |
