Submodelling: BCs in Abaqus
I am trying now to develop Python code which will automatize linking submodels to a given macromodel. I want that submodel is pre-created (using another software) and then linked to the main macromodel.
I am trying the following technique: after the main model is created and run, the code opens “Submodel.Cae” file (pre- created RVE model) in the same directory, renames it into “Submodel”, links it to “main” model, and then runs it.
- What is difference between boundary conditions and load in this case? If I place a box with voids (submodel) somewhere inside multilayer coating (macromodel, main) and define that all the BCs (on all 8 sides of the box) come from macromodel – do I need to define load as well?
- Submodel location: I use box dimensions and coordinates defined in the “Submodel.Cae” file, and if necessary, I move the submodel instances (box with voids) to where it should be in macromodel. Then, does Abaqus transfers the BCs/loads on submodel box borders automatically to submodel? Or do I need to find nodes in macromodel which should be linked to submodel?
