MeshIt 2010-2020

The tool MeshIT uses TRIANGLE http://www.cs.cmu.edu/~quake/triangle.html and TETGEN http://wias-berlin.de/software/tetgen to generate a quality tetrahedral mesh based on structural geological information.

This procedure is fully automatized and needs at least scattered data points as input!

Main developers: Mauro Cacace (mailto:cacace@gfz-potsdam.de) and Guido Blöcher (mailto:bloech@gfz-potsdam.de).

Some extensions were added by PERFACCT (www.perfacct.eu) by the following developers: Johannes Spazier Nihed Boussaidi Danny Puhan

The source can be compiled with some limitations on Windows, Linux and Apple. The limitation is the export of exodus file format used by Moose (https://github.com/idaholab/moose) which is only available for WIN64 (netcdf (https://www.unidata.ucar.edu/software/netcdf/) and exodus libraries (https://github.com/gsjaardema/seacas) are required). On all other platforms the following requirements are suggested and tested:

Windows:

-  Qt 5.9.9 for Windows 64-bit (VS 2015, VS 2017)

Linux:

-  Qt 5.9.9 for Linux 64-bit

Mac:

-  Qt 5.14.1 for OS X

Preparation:

• Create a copy of file meshit.pri.tmpl and save it as meshit.pri. Set either the EXODUS_LIBMESH variable or the EXODUS_LIBRARY variable to true if you want to enable the exodus export option.

• In case the exodus export (EXODUS_LIBMESH) was enabled, define the path to the root directory of a libmesh installation using variable LIBMESH (a compatible libmesh library is usually already installed as part of the Moose framework).

• In case the exodus export (EXODUS_LIBRARY) was enabled, define the path to the root directory of a netcdf installation and 'exodusII' installation.

Building:

• qmake meshit.pro
• make/nmake/mingw32-make
