The type of equation which is to be solved is specified through the EquationType
SOLVERINFO option in the session file. This can be set as in table 7.1. At present, the Steady
non-symmetric solvers cannot be used in parallel.
The solver info are listed below:
Continuousfor a C0-continuous Galerkin (CG) projection.
Discontinuousfor a discontinous Galerkin (DG) projection.
ExplicitRequires the use of an explicit time integration scheme.
ImplicitRequires the use of a diagonally implicit, IMEX or Implicit scheme.
ExplicitRequires the use of an explicit or IMEX time integration scheme.
ImplicitNot supported at present.
NonConservative(for CG only).
WeakDG(for DG only).
LDG(The penalty term is proportional to an optional parameter
LDGc11which is by default set to one; proportionality to polynomial order can be manually imposed by setting the parameter
LDGc11equal to p2).
The following parameters can be specified in the
PARAMETERS section of the session file:
epsilon: sets the diffusion coefficient ϵ.
d22: sets the diagonal entries of the diffusion tensor D.
lambda: sets the reaction coefficient λ.
The following functions can be specified inside the
CONDITIONS section of the session
AdvectionVelocity: specifies the advection velocity V.
InitialConditions: specifies the initial condition for unsteady problems.
Forcing: specifies the forcing function f.
