The procedure for the use of submodels can be easily described:

  • Generate a medium density mesh of shell or volume elements with your preprocessor

  • Analyse FE-model with your solver software, postprocess results and find critical points of the structure

  • Generate detailed submodels of shell or volume elements at critical locations

  • Use FEDIS to generate boundary conditions for the submodel

  • Analyse submodel(s) with your solver software
  • Postprocess high quality stress results and perform fatigue or fracture analysis
