About
-----
MAMMOTH is a wavelet-based multiresolution mesh generator, leveraging
the Triangle mesh generator for high-quality Delaunay triangulations.
Dependencies
------------
+ Triangle by J.R. Shewchuk {https://www.cs.cmu.edu/~quake/triangle.html}
+ LaGriT (Optional) {https://lagrit.lanl.gov}
/MAMMOTH/ provides tools to extrude the mesh in the vertical and
generate Exodus-II meshes. Since Triangle doesn't offer such
capabilities, this is done through the mesh generator LaGriT. If no
Exodus-II meshes are needed or another workflow is preferred, LaGriT
doesn't need to be installed.
Installation
------------
/MAMMOTH/ ships with a GNU makefile. Set your preferred C compiler and
build the code by executing
$ make; make clean
which will produce the executable `mammoth'.
Usage
-----
After building, the executable is located in the root directory.
$ ./mammoth -[a/m] <input-file>
The `-a` flag is set for carrying out the multiresolution analysis.
The `-m` meshes the domain.
See the example input folder provided alongside the code.
