SYMPTOM:
When using a non-reflecting boundary condition, the solver crashes on the first iteration.
PROBLEM:
Release 10.0 SP1 introduced a bug in the CFX-Solver initializing the 'old nonreflecting pressure' (needed for the LODI equations) on the first timestep.
WORKAROUND: Running the CFX-Solver in double precision may help to resolve this problem. Alternatively, do not install SP1 if you are using non-reflecting boundary conditions in you simulation. However, there are some improvements to this Boundary Condition type in Release 10.0 SP1, particularly for nonorthogonal elements at outflows. FIXED IN: Release 11.0. Custom 10.0 executable available upon request. |
