Profile Data Handling in Parallel Session

How profile data is handled in parallel?

The host reads the profile, and then this profile data is copied to each of compute cores. Since each core holds a copy, memory requirement per node will be equal to the number of cores on the node times the memory taken by the profile. For large profiles, this could pose a memory problem.

Sometimes profile is written from outside Ansys Fluent. Such files may be large. In these cases, please read it serial and initialize the case in Ansys Fluent. Then write profile file from Ansys Fluent. This profile file is much smaller which you can use in Ansys Fluent parallel.
