XCGD: cut-cell continuous Galerkin difference method

XCGD uses continuous Galerkin difference method to solve partial differential equations and perform structural topology optimization applications. XCGD is a header-only library.

Dependencies

• A2D
• SparseUtils
• algoim
• ParOpt

Installation

As XCGD is a header-only library, installation merely means moving headers and dependency metadata maintained in .cmake to a destination of the installation:

mkdir build_for_install && cd build_for_install && cmake .. -DXCGD_BUILD_TESTS=OFF -DXCGD_BUILD_EXAMPLES=OFF && make install

This installs XCGD headers and CMake files into ${HOME}/installs/xcgd.

To change this location, modify XCGD_INSTALL_DIR: cmake -DXCGD_INSTALL_DIR=<new location> <other args>.

Build examples

mkdir build && cd build && cmake .. && make -j

Test

cd build && ctest . -j <num_procs>
