This test case serves to verify the time and under-relaxation consistent
|
|
formulation developed by CFD@FSB group (University of Zagreb). Pressure is
|
|
probed at four corners and in the centre of the lid driven cavity. Five
|
|
simulations are performed with five different under-relaxation pairs:
|
|
1. alphaU = 0.8, alphap = 0.2
|
|
2. alphaU = 0.7, alphap = 0.3
|
|
3. alphaU = 0.6, alphap = 0.4
|
|
4. alphaU = 0.5, alphap = 0.5
|
|
5. alphaU = 0.4, alphap = 0.6
|
|
Tolerances for all equations are very small, yielding extremely small (O(1e-11))
|
|
differences in converged pressure field. If the differences are larger - it
|
|
means that the converged solution is not independent to relaxation factors.
