Simulation Parameters

The simualtion parameters are used to solve the incompressible Navier-Stokes problem.

The Simulation Parameters are defined in src/Commons/ParametersDef/StabilizationStruct.jl, where the default values are also provided.

sprob = StabilizedProblem()

The user is creating a StabilizedProblem using the default options. It is possible to specify:

  • method: VMS() or SUPG() where also the order of elements can be specified
  • coeff_method: TensorFormulation(), ScalarFormulation(). Stabilization coefficients r and Ci can be provided.
  • skew: enable a skew-symmetric formulation
sprob = StabilizedProblem(method=SUPG(1), coeff_method=TensorFormulation(Ci=[2,16], r=2), skew=true)

In this example the StabilizedProblem is using a SUPG resolution, using first order elements, a method to compute the coeffients based on the tensor formulation, with the supplied coefficients and a skew symmetric formulation of the conservation equations.
