DPM tracking coupled with standard k-omega turbulence model in v6.1.22 parallel solver
You may have an error like
0 (....srcmpsystem.c@1210): mpt_read: failed: errno = 10054 for DPM particle tracking in Fluent 6.1.22 parallel solver, when the Shared Memory parallel option for particle tracking and the standard k-omega turbulence model are used.
This defect was already fixed in Fluent 6.2.7. The workarounds in Fluent 6.1.22 or any version before v6.2.7 are
1) Switch to Message Passing parallel option for particle tracking vis Define/Models/DPM.
2) Switch to any other turbulence models, like SST k-omega, or k-epsilon model.
