Meshing Complex GeometrySteps in creating a mesh
Determine geometric features neededFault geometryTopographySharp structural boundariesMagma sources with complex geometry
Create spline curve (2D) or NURBS surface (3D) in CUBITIf using surface in several models export it for future useUse surfaces within CUBIT to webcut volumesChoose discretization according to type of problem
