Have you tried as the message suggests?

hi dear glenn
I tried several times and each time the error was immediately apparent, Now I did not deal with this error,What is your opinion about this error?
thanks

I have just posted on another thread where a cryptic error message was reported - and you have one as well. There is no publicly available description of what these obscure error messages mean - this is a significant failing of CFX.

You can really only try stuff and see what happens. Did this happen during partitioning? Try using another partitioning algorithm. Also lots of boundary conditions, domains or a long and complex flow path can confuse the partitioner.

yes it happened during partitioning, i put run mode on serial and problem is solved, i recivied other error about number of words in my model that i think induced high number of elements in model and timpe steps any dont move, and only mesh statistics in page do Move, please guide me
thanks

Your simulation is not huge, CFX can handle much bigger. There is something you have missed which is causing the memory problem.

Are you using 64 bit CFX on a 64 bit OS?

Have you tried different partitioning methods?

Have you tried the large problem partitioner? (See the Solver Manager documentation for information on this).

hi dear glenn
yes i using 64 bit cfx software on 64 bit os, with your help i put partitioning type on DRCB and dont get error but because limiting of the properties system i stopped my run for higher computation time it.
thanks for helping
beast regards
