Constructor & Destructor Documentation

◆ Kovasznay()

Functions::Kovasznay::Kovasznay ( const double  Re,
bool  Stokes = false 
)

Construct an object for the give Reynolds number Re. If the parameter Stokes is true, the right hand side of the momentum equation returned by vector_laplacians() contains the nonlinearity, such that the Kovasznay solution can be obtained as the solution to a Stokes problem.
