Build instructions

mkdir build
cd build
cmake ..
make

To enable trace logging, pass -DENABLE_TRACE_LOG=ON to CMake. (Note, that you also need to set the correct logging level when calling the executable.)

Run instructions

./cfdscope -h # print help about command-line arguments

Visualization runs

A good size for trying out the simulation and generating data for visualization is 64x64x64 grid cells.

OMP_NUM_THREADS=8 ./cfdscope -d 64 -e 5 -s 0.4

Benchmarking runs

To conduct performance measurements, use a larger simulation setup:

time OMP_NUM_THREADS=16 ./cfdscope -d 100 -e 6 -s 0.4

Visualization

The visualize.py script can be used to render a specific frame of the simulation with Paraview. To use it, first install Paraview via your system's package manager. See python visualize.py -h for available parameters.

Run visualization

pvpython visualize.py "<simulation_dir>/fields.csv.*" --frame 20 --size 64

Make sure to match the -size parameter to the grid size (-d) from the simulation call.

Tests

To run the tests, first enable their compilation at configure time by passing -DBUILD_TESTS=ON to CMake. Then, run:

tests/unittests
tests/integrationtests
