Hello all,
I am creating the mesh and having some trouble getting the layers added to a wall patch (base cell size = 2 mm, level of refinement = 4). The funny thing is, the layers were added correctly on a refinement level of 3, but not when the refinement level = 4. I am wondering what the problem is. If you can let me know the significance of a few variables in the sHMD, that would be great. Here is the snippet of the concerned section of sHMD: addLayersControls { relativeSizes true; //false means thickness values are absolute.True means values are relative to surface mesh dimension. //list patch names inside "layers" to add cell layers to those patches layers { wall_imported { nSurfaceLayers 3; } } expansionRatio 1; finalLayerThickness 0.33; minThickness 0.05; nGrow 0; //WHAT DOES THIS VARIABLE DO?? // Advanced settings featureAngle 180; //WHAT DOES THIS VARIABLE DO?? nRelaxIter 20; nSmoothSurfaceNormals 1; nSmoothNormals 3; nSmoothThickness 10; maxFaceThicknessRatio 0.5; //WHAT DOES THIS VARIABLE DO?? maxThicknessToMedialRatio 0.3; //WHAT DOES THIS VARIABLE DO?? minMedianAxisAngle 80; //WHAT DOES THIS VARIABLE DO?? nBufferCellsNoExtrude 0; nLayerIter 50; } |
