Detailed Description

The parameters common to matrix and residual computations. The vectors viscosity, resistance, and graddiv_stabilization are indexed by the cell material id and represent the coefficients in the system.

The coefficients refer to the equations described in the namespace Brinkman.

Constructor & Destructor Documentation

Brinkman::Parameters::Parameters ( )

inline

Default constructor, only setting the Saffman friction parameter.

Brinkman::Parameters::Parameters ( double  resistance )

inline

Constructor, initializing default values for viscosity and resistance. These refer to a situation with two subdomains, one Darcy and one Stokes. They are zero resistance and viscosity one in material 0 (Stokes). In material 1 (Darcy), the viscosity is 0 and the resistance is the function argument.
