SurfaceLayers on a endless circular cylinder
1 Attachment(s)
hi foamers!
I have a problem with my surfacelayers. i use to simulate a flow over a endless circular cylinder. How you can see on the picture my layers do not go till the frontAndBack-patches. Is it normal that the layers where built from the outside-patches? I am new in OpenFOAM please help me! // Settings for the layer addition. addLayersControls { relativeSizes true; // Per final patch (so not geometry!) the layer information layers { geodata1_patch0 { nSurfaceLayers 7; } } // Expansion factor for layer mesh expansionRatio 1.0; //- Wanted thickness of final added cell layer. If multiple layers // is the // thickness of the layer furthest away from the wall. // Relative to undistorted size of cell outside layer. finalLayerThickness 0.9; //- Minimum thickness of cell layer. If for any reason layer // cannot be above minThickness do not add layer. // Relative to undistorted size of cell outside layer. minThickness 0.1; //- If points get not extruded do nGrow layers of connected faces that are // also not grown. This helps convergence of the layer addition process // close to features. nGrow 1; best regards Wolfgang |
Hi Wolfgang
I noticed the same thing, but as I'm not very experienced in meshing either, I don't know if this is normal, or just our mistake... Best regards Silvan |
Hi Wolfgang,
try this : set your front+back from patches to empty. then run snappy. if the layers are ok and you want to run your case you have to manually overwrite the front+back in your boundary file ( from empty to wall/etc. ). hope it works |
