Working with incompatible Mesh Models

In many engineering applications it is necessary to transfer simulation or experimental results from one model into another. Such cases are for example

  • thermal loads on structures which are in contact with warm fluids,
  • fluid forces on deformable components,
  • manufacturing history (material and geometry properties) to initialize crash calculations,
  • comparison of simulation and experimental results,
  • and many more.

Each simulation area or analysis discipline has its own discretisation and preferred element types, mesh densities, and rules for required geometric compliance. The realization of software solutions for such multi-physics applications therefore often is hindered by incompatible mesh geometries and discretisations used in the combined models. Also the complexity and size of models requires a neighborhood and mapping calculation for production models of e.g. automotive underhood or turbine interiors need advanced, fast and scalable algorithms running on modern multi-core architectures.
