PropertyManager
PropertyManager owns and manages MFEM coefficient objects, handling the set-up of piecewise coefficients defined across multiple materials.
Overview
PropertyManager owns and manages mfem::Coefficient, mfem::VectorCoefficient, and mfem::MatrixCoefficient derived objects added to the MFEM problem. It also handles the set-up of global piecewise coefficients constructed from multiple coefficients defined on separate subdomains of the mesh.
End users should not usually need to interact with the PropertyManager directly, instead defining Materials for all subdomains of their mesh which will add properties using the PropertyManager internally. Developers wanting to add new coefficients to the MFEMProblem should do so using the PropertyManager::declareXXX methods, and use getScalarProperty, getVectorProperty, and/or getMatrixProperty to fetch global coefficients for properties in the system by name.
