FiniteElementData

FiniteElementData[]

represents data in NDSolve`StateData that is used for the finite element method.

Details and Options

  • FiniteElementData[] is created by NDSolve`ProcessEquations.
  • FiniteElementData[] can be extracted from NDSolve`StateData objects using the "FiniteElementData" property.
  • In standard output format, only the degrees of freedom are shown.
  • FiniteElementData objects may be used to extract BoundaryConditionData, FEMMethodData, and PDECoefficientData.
  • FiniteElementData[][prop] gives the property prop of the FEMMethodData object. The following properties may be given:
  • "BoundaryConditionData"extract processed boundary condition data
    "FEMMethodData"extract finite element method data
    "PDECoefficientData"extract processed equation data
    "Properties"list of properties
    "Solution"extract the current state vector if available
