Util_convert_hex2tet_mesh

Data Structure: Util_convert_hex2tet_mesh

Description

Convert a Hexahedral element mesh to a Tetrahedral element mesh

Usage

Util_convert_hex2tet_mesh     NUM=ival   where ival  is the data structure number

Description

Overview

The Util_convert_hex2tet_mesh can be used to convert a hexahedral mesh to a tetrahedral element mesh. This requires a datafile with:

•1 - Geometry_data to read the .geo file containing the hexahedral meshed geometry

•2 - Mesh_control_data and Unstructured_mesh_data defining the parameters for the new tetrahedral mesh

Notes

•The initial .geo file with the hexahedral mesh must have full definition of the geometry (i.e. all volumes must be defined by enclosing surfaces, all surfaces must be defined by enclosing lines) .

•All geometry sets present in the original hexahedral .geo file will be converted to the appropiate geometry set type for the tet mesh (i.e. geometry sets type "nodal" containing a list of nodes from the hex mesh will be converted to geometry sets containing the corresponding surfaces).
