ExternalProblem

Intermediate class that should be used as an extension point (inheritance) for externally coupled codes (MOOSE-Wrapped Apps). The external coupling interface should override the "solve" method along with a method for testing convergence of the last solve.

More information on using the ExternalProblem for wrapping applications may be found in the application development documentation.

Examples

  • External Petsc Application

The ExternalPetscProblem inherits from the ExternalProblem to run a pure PETSc solver. It is also able to sync the PETSc solutions to MOOSE variables.

  • Cardinal

Cardinal is an open source coupling of MOOSE with the Monte Carlo code OpenMC and the spectral element CFD code NekRS, which are both external solvers and not MOOSE-based applications. The ExternalProblem is used to order the solves and custom transfers were implemented to pass fields between each application.
