2.2.3. Multi-stage Multi-scale Modelling The submodeling is a technique used to study a local part of a model with a refined mesh based on interpolation of the solution from an initial global model. The usage of this technique is most useful when it is necessary to obtain an accurate and detailed solution in a local region and detailed modeling of that local region has negligible e ff ect on the overall solution. The submodeling can use a combination of ABAQUS / Explicit and ABAQUS / Standard with combination of linear and nonlinear procedures. Di ff erent element types can be used in the submodel than those used to model the corresponding region in the global model. The submodeling types provided for global-to-submodel applications are:

1. Two-dimensional models
