Cylinder and dsmc solver
 
Hi!

I've made cylinder geometry via blockmesh utility and started dsmc solver, but the process have eaten too much memory and show an error exception:

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It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library
Aborted

Same case with cube geometry solve good.

Can you help me, please?

blockMeshDict file:

Sounds like you have too many particles.

The information you have posted is not sufficient.
Could you also post the contents of constant/dsmcProperties ?
