Hi folks,
When trying a 'tet' in blockmesh I get a Sig11. Below is my file (slightly condensed), and underneath the console result. Is it forbidden to use 'tet' in blockMesh? And if not, what am i doing wrong? It looks that everything goes well until the merge list. Code:
FoamFile { version 2.0; format ascii; class dictionary; object blockMeshDict; } convertToMeters 1; vertices ( (0 0 0) (1 0 0) (0 1 0) (0 0 1) ); blocks ( tet (0 1 2 3) (20 20 20) simpleGrading (1 1 1) ); boundary ( xy { type patch; faces ( (0 2 1) ); } yz { type patch; faces ( (0 3 2) ); } zx { type patch; faces ( (0 1 3) ); } r { type patch; faces ( (1 2 3) ); } ); Code:

Greetings devlaam and welcome to the forum!AFAIK, in the official OpenFOAM version, blockMesh can only handle "hex" blocks.
For getting tet-like blocks, you need to collapse edges, as explained near the end of this page: http://www.openfoam.org/docs/user/blockMesh.php Best regards, Bruno

Thank you wyldckat, for taking the time to answer my question.
Yes, i found that out in the mean time. I was put in the wrong direction because blockMesh does not reject the input but starts processing. I assumed, like happens when you put invalid keywords in dictionaries in general it would report that, and not generate a segmentation fault. Pretty drastic response to my taste! |
