Hi, all
I have a problem with blockMesh utility
I'm trying to generate simple 3D rectangular mesh with number of cells 500*500*500. If I try to generate mesh 50*50*50 everything works fine, but in this case following message appears:

new cannot satisfy memory request.
This does not necessarily mean you have run out of virtual memory.
It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library

--> FOAM FATAL ERROR : Cannot find file "points" in directory "constant/polyMesh"

From function Time::findInstance(const word& dir, const word& name)
in file db/Time/findInstance.C at line 133.

FOAM exiting
It seems that problem is the lack of memory for so large mesh.
How can I solve this problem?

Best regards,
Efimenko Evgeny

Get a 64bit machine with a lot of memory.

125M cells =~ 50GB and thats without any fields.

I think another option is to try to run in parallel, or try to split your problem in smaller parts if possible
