Hi !
If I click on button Iterate, FLUENT don´t compute and write this :

Warning: ST_Malloc: out of memory.malloc_storage: unable to malloc pp, size 27541160, t 7, myid 1000000.

Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: ()

Can anybody tell me, pleas, what can I do with it ?
Thank you very mutch !

Error message in Fluent sometime might not mean anything. just a minor program bug. just restart Fluent and do it again.

If keep repeating, i think ur hardware and OS might have problem.

you are asking more RAM memory than you PC can afford.
Reduce your mesh, or switch to parallel process (eventually a PC with more RAM memory)
Usually a 1 million cells mesh will ask 1 GB Ram memory

Yes, it is lack of RAM.. you can try also to convert the mesh into polyedral.....
