ADV-1: Contact problem
Note
Prerequisites of this tutorial include VEC-0: Linear elasticity


Note
Intended learning outcome:
  • general structure of a program developed using MoFEM
  • idea of Simple Interface in MoFEM and how to use it
  • idea of Domain element in MoFEM and how to use it
  • Use default Forms Integrals
  • how to push the developed UDOs to the Pipeline
  • utilisation of tools to convert outputs (MOAB) and visualise them (Paraview)
