This is a place to provide bug information on FLUENT. Please make sure that it is really a bug. Try and provide some indication of what circumstances the bug occured. Somethings work fine 99% of the time. If this is a limited circumstance issue, it is still a bug, but be clear when it can be expected to occur.

Parallel Issues

Many features of Fluent do not work properlly in parallel. Some of these are trapped by the Cortex interface, some are not. Some of these are documented, some are not.

Merging Fluid Zones

When running in parallel merging fluid zones may result in an irrecoverable grid error. If you run a grid check you will find errors that the number of nodes found does not match the expected. This has been confirmed for a 21 million cell grid with some mixed cell type zones and some all hex zones. It is possible it may not occur under other circumstances.
