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;
}
