8.5. PFEM testΒΆ

test('PFEM', tolv, tolp, tolrv, tolrp, tolrelv, tolrelp, iter, maxincr, pFlag=0, nType=2)

Create a PFEM test, which check both increments and residual for velocities and pressures.

tolv (float) Tolerance for velocity increments
tolp (float) Tolerance for pressure increments
tolrv (float) Tolerance for velocity residual
tolrp (float) Tolerance for pressure residual
tolrv (float) Tolerance for relative velocity increments
tolrp (float) Tolerance for relative pressure increments
iter (int) Max number of iterations to check
maxincr (int) Max times for error increasing
pFlag (int)

Print flag (optional):

  • 0 print nothing.
  • 1 print information on norms each time test() is invoked.
  • 2 print information on norms and number of iterations at end of successful test.
  • 4 at each step it will print the norms and also the \(\Delta U\) and \(R(U)\) vectors.
  • 5 if it fails to converge at end of numIter it will print an error message but return a successfull test.
nType (int) Type of norm, (0 = max-norm, 1 = 1-norm, 2 = 2-norm). (optional)
