Sloped Mesh | Backward Facing Step
Dear FOAMers,
i want to build a parameterized model of a backward facing step: http://www.cfd-online.com/Forums/peo...nwi/sloped.pnghttp://people.fh-landshut.de/%7Emehrenwi/sloped.png As i want to have all dimensions variable, i created a blockMeshDict.m4-file which you can see below: Code:
/*--------------------------------*- C++ -*----------------------------------*\ http://people.fh-landshut.de/%7Emehrenwi/Mesh.png Is there any option to get better mesh results at the end of the slope at the outlet? Thanks in advance, Mathias |

Dear Mathias,
looks like you make some progress with your calculations Perhaps I can also help you with this problem. Attached you find a sketch of a proposed domain decomposition which avoids highly skewed cells. I hope with this decomposition it is still possible to parametrize your domain. good luck Colin Edit: I forgot to mention an additional layer of blocks for the separated water inlet: Just include another line between the top and the middle line. I know its quite self explaining, but for the sake of completeness. |
Good morning Colin,
thank you very much, i think is a nice idea to get not so bad shaped elements! |
Hi Colin,
i implemented your suggestions into my blockMeshDict.m4-file, below you can see the resulting mesh, it looks really nice, thank you very much (again)! http://people.fh-landshut.de/%7Emehr...esh_better.png |
