README

This project is the implementation of paper "Explicit Topology Optimization of Conforming Voronoi Foams".

The head files and library files are provided, along with an example of femur in paper. The library files were generated in Linux_x86_64 platform.

1. Dependence

Our project is implemented in C++ and built using cmake, having some dependences as follows:

• TBB
• SuiteSparse (the CHOLMOD therein)
• Boost
• OpenMesh
• CGAL
• OpenMP
• geogram
• fmt

2. Compile and Run

Run following commands in terminal

mkdir build && build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j16
./work

This will run the femur example set in main.cpp, and the following important settings in main.cpp are commented:

1. t, tmin, tmax: initial, minimum, maximum width of rods
2. scalarE: weight of shape energy
3. volfrac: volume fraction

The results are to be stored in the output/femur directory, including:

1. C.txt, E.txt, V.txt: compliance, shape energy and volume fraction of each iteration
2. model/model_i.txt: rod information of #iter-i, i.e. two endpoints and radius of rod
3. X/X_i.txt: varibles of #iter-i, i.e. seeds positions and radii
