tandem
A scalable discontinuous Galerkin code on unstructured curvilinear grids for linear elasticity problems and sequences of earthquakes and aseismic slip
Features • Dependencies • Installation • Documentation • Citing tandem • License
Features
- High-order discontinuous Galerkin finite element method
- Solver for elastostatic problems and SEAS problems
- Unstructured triangle and tetrahedral meshes
- Curvilinear representation of boundary
- Native support for Gmsh's MSH file format version 2 (including high-order meshes)
- Sub-element material parameter resolution
- Efficient matrix-free and assembly kernels for many CPU architectures (using YATeTo)
- Scalable on distributed memory architectures; access to many linear solvers via PETSc
- Supports discrete Green's function for SEAS
For a general overview of the project check out our presentation at virtual EGU 21.
Dependencies
tandem relies on the following open-source projects: * zlib * Eigen * Python with NumPy * Lua * CMake * METIS and ParMETIS * MPI (e.g. OpenMPI) * PETSc * libxsmm (optional)
Installation
For information on installing the dependencies and a detailed guide to installing Tandem, check out the installation guide.
You need a recent C++17 compiler (GCC ≥ 8.0 or clang ≥ 8)) and you need to install the dependencies. Then install using the following commands:
bash
$ git clone https://github.com/TEAR-ERC/tandem
$ cd tandem/
$ git submodule update --init
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_C_COMPILER=mpicc -DCMAKE_CXX_COMPILER=mpicxx -DARCH=hsw -DPOLYNOMIAL_DEGREE=4 -DDOMAIN_DIMENSION=2
$ make -j
Here the following options were used: * CMAKECCOMPILER and CMAKECXXCOMPILER: Select MPI compiler wrappers * ARCH: Optimize for Intel Haswell (see cpuarchflags.cmake for more options) * POLYNOMIALDEGREE: The polynomial degree of the finite element spaces * DOMAINDIMENSION: Set 2 for triangle meshes and 3 for tetrahedral meshes
