Creation of Hexa mesh on 3D CAD geometry

Posted by mihe at October 29. 2021

Hi, What algorithm are you using to create hexa mesh on 3D CAD models?

My experience is only from "Extrusion 3D". I then use 1D algorithm: Local length, 2D(submesh) algorithm Netgen + "Quad-dominated" and 3D algorithm "Extrusion 3D". These algorithms work ok for some shapes but essentially the geometry must be divided up in parts each being 2D and then extruded from that.

-How do you proceed to overcome this for more complex shapes? -What algorithm are you using?

-Anybody using the plugins DISTENE "MG-" algorithms? -Are they good? -Easy buy and install?

actually, some people would simply avoid hexa-meshing :)

while using thetra-automatics....

Yes but in contact analysis HEXA has great advantages. -No body using the plugins DISTENE "MG-" algorithms?

There is in Salome 9.7 the new module HexaBlock allowing to build a model of blocks associated with the geometry and hexmesh them Johannes_ACKVA www.code-aster.de Training & Support SalomeMeca and Code-Aster *** NEW: all Code-Aster courses now as Video and Webinar courses ***
