Gmsh mesher : Quasi-Structured Quad & Hex-Dominant

[synt]

@Matej

So, I was even thinking of preparing my own code to create an extruded or revolved mesh based on the mesh of the base surface.

indeed, a feature in further processing based on existing surface mesh successfully generated by Gmsh is required. It can be used as purpose of extrusion or revolving of :

• base 2D mesh from quasi-structured quad mesh results
• midside nodes of quadratic element to follow geometry of revolve curved path
• normal extrusion of complex 3D Nurbs

@Matej

is actually implemented in Gmsh

sure, it has been implemented. R-tree algorithm option is available in version of 3.x but later is deactivated by developer due to some reason.

a user only need to reference part or geometry files (step,iges,brep), below geo file input format which can be used as template.

Merge "part.igs";

Mesh.CharacteristicLengthFactor = 0.25;

Mesh.Algorithm = 9;
Mesh.Algorithm3D = 9;
Mesh.Optimize = 1;
Mesh.Recombine3DAll = 1;
Mesh.Smoothing = 0;

Mesh.RemeshAlgorithm = 0;
