Mesh generator for Lattice Element Method

Lattice Element Method - GMSH (lem-gmsh)

Cambridge Berkeley - Geomechanics

Install dependencies

• Docker image for CB-Geo lem-gmsh code https://hub.docker.com/r/cbgeo/lem

• Instructions for running lem docker container: https://github.com/cb-geo/docker-lem/blob/master/README.md.

Create a GMSH file

• Make sure gmsh is installed.

• To generate a mesh file in 3D (for example to mesh the bin/tension.geo) run gmsh -3 tension.geo, this will create a tension.msh file, which can be found in the bin/ directory as well.

Compile and Run

0. Run mkdir build && cd build && cmake -DCMAKE_BUILD_TYPE=Release /path/to/CMakeLists.txt

1. Run make clean && make -jN (where N is the number of cores)

2. Run lem-gmsh ./lem-gmsh /path/to/meshfile.msh this will generate a nodes.txt file in the build directory.
