fastMarchingFoam

The shortest path algorithm on the surface of OpenFOAM meshes.

Note: the code from the geodesic subdirectory is a clone of the geodesic project (the downloadable zip file geodesic_cpp_03_02_2008.zip). This project is licensend under the MIT License. See geodesic/readme.txt for further information.

Requirements

The code was developed using OpenFOAM-2.3.x. It might or might not work with newer versions of OpenFOAM (please test and let me know).

Installation

1. Download source

git clone https://github.com/fospald/fastMarchingFoam.git

2. Run Allwmake, which uses the wmake tool of OpenFOAM

sh Allwmake

This should build the fastMrchingFoam solver.

Run Demo

The demo consists of a simple 1x1x2 box. The points and distance field names are specified in constant/fastMarchingDict. For this demo a distance filed d is generated, which gives the shortest distance to the point (0.0 0.2 0.5). The maxDist parameter can be used perform the distance calculation only up to distance maxDist (in order to save computation time). Larger distances are then set to maxDist.

cd demo
sh Allrun

This should run the solver, convert the results to VTK and open them in ParaView.
