Problem System

Tensor solvers perform time integration of the Solve operators in the simulation.

Example Input File Syntax

Available Objects

  • Moose App
  • DisplacedProblemA Problem object for providing access to the displaced finite element mesh and associated variables.
  • DumpObjectsProblemSingle purpose problem object that does not run the given input but allows deconstructing actions into their series of underlying Moose objects and variables.
  • EigenProblemProblem object for solving an eigenvalue problem.
  • FEProblemA normal (default) Problem object that contains a single NonlinearSystem and a single AuxiliarySystem object.
  • ReferenceResidualProblemProblem that checks for convergence relative to a user-supplied reference quantity rather than the initial residual
  • Marlin App
  • LatticeBoltzmannProblemProblem object to enable solving lattice Boltzmann problems
  • TensorProblemA normal Problem object that adds the ability to perform spectral solves.
