Hello together,
I get the following error when trying to add layers to my geometry: Code:

Update:
my SHM layer section looks like: Code:
// Settings for the layer addition. addLayersControls { // Are the thickness parameters below relative to the undistorted // size of the refined cell outside layer (true) or absolute sizes (false). relativeSizes false; // Per final patch (so not geometry!) the layer information layers { flange_CATIA { nSurfaceLayers 3; } } // Expansion factor for layer mesh expansionRatio 1.1; // Wanted thickness of final added cell layer. If multiple layers // is the thickness of the layer furthest away from the wall. // See relativeSizes parameter. finalLayerThickness 0.001; // Minimum thickness of cell layer. If for any reason layer // cannot be above minThickness do not add layer. // See relativeSizes parameter. minThickness 0.000000000000001; // 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 0; // Advanced settings // When not to extrude surface. 0 is flat surface, 90 is when two faces // are perpendicular featureAngle 90; // Maximum number of snapping relaxation iterations. Should stop // before upon reaching a correct mesh. nRelaxIter 10; // Number of smoothing iterations of surface normals nSmoothSurfaceNormals 50; // Number of smoothing iterations of interior mesh movement direction nSmoothNormals 50; // Smooth layer thickness over surface patches nSmoothThickness 100; // Stop layer growth on highly warped cells maxFaceThicknessRatio 0.8; // Reduce layer growth where ratio thickness to medial // distance is large maxThicknessToMedialRatio 0.9; // Angle used to pick up medial axis points minMedianAxisAngle 130; // Create buffer region for new layer terminations nBufferCellsNoExtrude 0; // Overall max number of layer addition iterations. The mesher will exit // if it reaches this number of iterations; possibly with an illegal // mesh. nLayerIter 50; // Max number of iterations after which relaxed meshQuality controls // get used. Up to nRelaxIter it uses the settings in meshQualityControls, // after nRelaxIter it uses the values in meshQualityControls::relaxed. nRelaxedIter 100; } I will post some picture afterwards... |
