| double | mean_pressure |
Flow solution in 2D by Kovasznay (1947).
This function is valid on the half plane right of the line x=1/2.

| 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.
