| Summary | 0003849: 1024^3 grid can not be created by blockMesh | ||||
| Description | I tried to create 1024 cell all three direction totally order of 1 billion cell but I couldn't get it. blocks ( hex (0 1 2 3 4 5 6 7) (1024 1024 1024) simpleGrading (1 1 1) ); I tried this on hpc system which has 510 gb memory. Output of blockMesh can be found in attachment. I tried to get same mesh on my computer (64gb memory) by Pointwise v18.1R2 and I could create mesh. Pointwise create 150gb polyMesh files for this mesh. So it is not memory issue. When I tried to use polyMesh files which created by Pointwise I came a cross error might be same problem in blockMesh it exceed the integer limit. Number of faces exceed the limit of integer. --> FOAM FATAL IO ERROR: (openfoam-2012) incorrect first token, expected <int> or '(', found on line 10: double 3.21494e+09 I guess when OpenFOAM was written no one think about face number can exceed integer limit )) | ||||

To create a mesh with that many cells you will need to compile OpenFOAM-9 or dev with 64bit labels. > I guess when OpenFOAM was written no one think about face number can exceed integer limit I did and added 64bit label support as an option. |
