panfactory / panslbm2

is a tiny library for topology optimization using Lattice Boltzmann method (LBM).

PANSLBM2

A library of Topology Optimization with LBM.

Usage

Setup

Clone source codes into your environment.
Although your environment is allowed Windows, Linux or MacOS, use Windows for example bellow.

git clone https://github.com/PANFACTORY/PANSLBM2.git && cd PANSLBM2

After that, working directory is PANSLBM2/.

2D heatsink

For example, run a program solving 2D steady-state heatsink problem.
Use MinGW with AVX2 and OpenMP.

g++ -mavx -fopenmp -o build/heatsink.exe production/heatsink.cpp

build/heatsink.exe

And results are output in result/.
Of course, you can also use other compilers like Intel C++ Compiler.

3D heatsink

For example, run a program solving 3D steady-state heatsink problem.
Use MinGW with AVX2, OpenMP and MicrosoftMPI.

You have to place two files in your working directory to use MicrosoftMPI.

• libmsmpi.a
• msmpi.def

And add or uncomment #define _USE_MPI_DEFINES at 1st line in production/heatsink3D.cpp.
After that, build and execute with these commands.

g++ -mavx -fopenmp -lmsmpi -L . -o build/heatsink3D.exe production/heatsink3D.cpp

mpiexec -n 4 build/heatsink3D.exe 2 2 1

And results are output in result/.
Of course, you can also use other compilers like Intel C++ Compiler and other MPI libraries like Intel MPI.

Dependency

• AVX2
• OpenMP
• MPI
