I'm using rhoSimpleFoam to calculate flow over airfoil. And after several iterations the Ux seem to be zero in the inlet. Also the temperature have some problems.
This is my case http://pan.baidu.com/share/link?shar...&uk=2234161950 And the mesh http://pan.baidu.com/share/link?shar...&uk=2234161950 Also, the checkMesh Checking geometry... Overall domain bounding box (-14.9978 -15 -0.424248) (15 15 0.424248) Mesh (non-empty, non-wedge) directions (1 1 0) Mesh (non-empty) directions (1 1 0) All edges aligned with or perpendicular to non-empty directions. Boundary openness (3.30002e-18 -1.7807e-18 -1.66129e-18) OK. Max cell openness = 1.08077e-14 OK. Max aspect ratio = 595.261 OK. Minumum face area = 7.97538e-09. Maximum face area = 1.29329. Face area magnitudes OK. Min volume = 6.76708e-09. Max volume = 0.341398. Total volume = 681.489. Cell volumes OK. Mesh non-orthogonality Max: 80.4107 average: 22.3043 *Number of severely non-orthogonal faces: 26. Non-orthogonality check OK. <<Writing 26 non-orthogonal faces to set nonOrthoFaces Face pyramids OK. Max skewness = 0.864702 OK. Mesh OK. End What fvScheme will you suggest? Last edited by yzf1215; November 28, 2012 at 20:57. Reason: Adding information of checkMesh |

Hi!
First of all I'll try to correct the error that checkMesh gives to you Quote:

I have tried this way, eliminated the non-otrhogonal mesh, but the calculation still blows up.
