SeismicMesh is distributed under the GP元 license and more details can be found in our short paper. SeismicMesh can also produce mesh-density functions from seismological data to be used in the mesh generator. ![]() For increased efficiency, the core package is written in C++, works in parallel, and uses the Computational Geometry Algorithms Library. As an implementation of DistMesh, it produces high-geometric quality meshes at the expense of speed. SeismicMesh is a Python package for simplex mesh generation in two or three dimensions.
