Submodeling

[Balaa]

Dear all,
I would like to do submodeling for my research problem.
I have doubt on; how to define cut boundary in the global model to submodel.

If it is displacement based or force based; how to define the boundary
condition.

I would appreciate all your help in this regard.

What there is to understand about submodeling is that it is a "2-step" process. In the first one, you define the superelement, telling ABAQUS what nodes of the submodel "define" the element. It then computes the stiffness matrix, and your submodel effectively becomes a "normal" element you can incorporate to your simulation. In the second step, you use this element as any other, i.e. boundary conditions and concentrated loads are applied at the nodes as usual.

If you need detailed results within the submodel after the simulation, ABAQUS allows you to recover those as well, it is described in the manual.

Hope this helps,
Fernando

You have to basically match the geometries in two models and let Abaqus
identify the boundaries. Also you can define the surface or element set for
extracting the global model results.
