A simple variational tetrahedral mesher based on Geogram library. Compute the inner tetrahedral mesh based of the given 2D closed mesh.
Installation is done in 2 steps: installation of the Geogram library and compilation of the variational mesher.
-
Clone Geogram library
-
Install the library header required:
sudo apt install libboost-dev libcgal-dev libglu1-mesa-dev libxxf86vm-dev libxtst-dev libxrandr-dev libxinerama-dev libxcursor-dev doxygen cmake g++
- Open a terminal in the clonned Geogram folder and run in the terminal:
./configure.sh
cd build/Linux64-gcc-dynamic-Release
sudo make -j4 install
You may have to install other if error during configuration or compiling occur below.
-
Clone this repository.
-
Compile the mesher with
g++and include the required folder and library, something like (on Ubuntu):
g++ var-tet-mesher.cpp -o Var-Tet-Mesher -I/usr/local/include/geogram1/ -lgeogram
- The mesher is ready
The variational mesher is called by specifying first the input surface mesh, the output file and the number of points desired through nb_pts=X with X the number of points.
For example:
./Var-Tet-Mesher cylinder.mesh out.mesh nb_pts=500
to mesh the inner volume of the closed surface in cylinder.mesh with 500 points.
Maximum number of threads (for parallel meshing) could be specified using the argument max_threads=X (default all the thread available).
A Python plugin was created to allow using the variational tetrahedral mesher directly from the GUI of the Salome SMESH module.
See README.md file in the salome_var_tet_mesher directory for more information.
