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 It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library Aborted Same case with cube geometry solve good.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: Code:
FoamFile { version 2.0; format ascii; class dictionary; object blockMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // convertToMeters 0.01; vertices ( (-1 -1 -1) (1 -1 -1) (1 1 -1) (-1 1 -1) (-1 -1 1) (1 -1 1) (1 1 1) (-1 1 1) ); blocks ( hex (0 1 2 3 4 5 6 7) (5 5 5) simpleGrading (1 1 1) ); edges ( arc 0 1 (0 -1.4142135623730951 -1) arc 1 2 (1.4142135623730951 0 -1) arc 2 3 (0 1.4142135623730951 -1) arc 3 0 (-1.4142135623730951 0 -1) arc 4 5 (0 -1.4142135623730951 1) arc 5 6 (1.4142135623730951 0 1) arc 6 7 (0 1.4142135623730951 1) arc 7 4 (-1.4142135623730951 0 1) ); patches ( patch sides ( (1 5 4 0) (0 4 7 3) (2 6 5 1) (3 7 6 2) ) patch inlet ( (0 3 2 1) ) patch outlet ( (4 5 6 7) ) ); mergePatchPairs ( ); Last edited by sandre; July 2, 2011 at 08:21. |

Sounds like you have too many particles.
The information you have posted is not sufficient. Could you also post the contents of constant/dsmcProperties ? |

hi , the problem occurs because of you defined too many particle per cells .
use the file named dsmcProperties in the constant folder and change the nEquivalentParticles in there . the number had some rules to define and for that look at here : https://www.researchgate.net/profile...geometries.pdf bests . |
