KNOWN ISSUE: Diffusion discretization at non-overlap GGI boundaries may use volume fraction instead of contact area fraction (Class 3 Error)
|
SYMPTOM: The diffusion term discretization at non-overlap GGI boundary conditions may use volume fraction where it should use contact area fraction. This will not normally lead to a large error, but the error may be significant for cases where molecular thermal conductivity is large (e.g. liquid metals). PROBLEM: This is due to the use of uninitialised local variables in the CFX-Solver. WORKAROUND: No workaround is currently available. FIXED IN: ANSYS CFX Release 12.1. A custom executable for ANSYS CFX Release 12.0 is available on request. |
