Hello,

I am running a 3ddp case, meshed using GAMBIT and then exported to FLUENT.

The number of cells of my grid is 2160000.

Its giving me the following error

[b:60a77ba75e][color=blue:60a77ba75e]Warning: ST_Malloc: out of memory.malloc_storage: unable to malloc Z Velocity Gradient, size 92651040, t 2, myid 1000000.

Error:

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: ()[/color:60a77ba75e][/b:60a77ba75e]

------------------------------------------------------------------------------

My system is a Windows XP 32 bits with 4 GB of RAM, although the Memory Status application of Fluent says that I have got 2004012 KB of physical memory plus 2047724 KB of page memory.

Anyone who have some idea please help me.

Many thanks,

Ivan.

hi,

anything over 1 million cells requires a fluent parallel solver. check if your PC has multiple processors, and then issue the command

fluent 3ddp -tx

where x is the number of processors you have. various things change when you run fluent in parallel so i recommend you consult the manual.

otherwise, ule need to get your hands on a cluster!
