The application includes tests to check the proper functioning of the application.

😎 Features:

  • Mesh tying conditions based in mortar formulation

  • Augmented Lagrangian contact conditions based in mortar formulation

    • Frictionless formulation

    • Frictional formulation

  • Penalty contact conditions based in mortar formulation

    • Frictionless formulation

    • Frictional formulation

  • Simplified MPC conditions based in mortar formulation. With the mortar formulation the weight are computed, allowing to compute a Simplified NTN and a simplified NTS

    • Frictionless formulation

    • Frictional formulation

    • Mesh tying formulation, with tension checking

  • Self-contact compatible

  • Strategies, processes, solvers and convergence criterias used by the contact formulation

  • Several strategies for adaptive remeshing

  • The application includes search utilities in order to create the contact conditions

  • Frictional laws (WIP) in order to consider different types of frictional behaviour

  • +115 Python unittest, including Validation tests, and +85 cpp tests

⚙️ Examples:

Examples can be found here, and here for several contact adaptive remeshing examples.
