I newly installed Fluent 14 but it is very slow in parallel processing.
I used Fluent 13 for running on a multicore processor but when I use same case/data files on FLUENT 14 take much longer cpu time on same processor. I run transient simulation and everything is same. Any idea what wrong is? thanks

Maybe it's some problem with mpi version or interconnect option you use? (in ansys14 by default - "mpi local parallel" instead of "mpi-hp")
Check latency between threads (cores) in 13 and 14 versions (in "parallel" menu).

You are right villager.
The mpi default version for Fluent14 is pcmpi but for Fluent13 is hp-mpi. Fluent14 doesn't have hp mpi. I checked other options for mpi in Fluernt14 but all give me much longer processing time. Does anybody know how to get hp-mpi in Fluent 14 or how to do to resolve this problem? I appreciate any help.
