VolcFlow C

VolcFlow-C : One fluid simulation program over a digital terrain model in C language

This standalone C language software simulates one flow over a Digital terrain Model (DTM) with cohesion threshold, density and viscosity rheological parameters. The algorithm is extracted from VolcFlow one fluid version under MatLab. VolcFlow-C is integrable into various platforms as VRVOLC for flow simulation in Virtual Reality, University Clermont Auvergne Mesocentre, or VICTOR computing infrastructure at Columbia University. Source code is optimised for shared memory parallelisation with OpenMP.

2.5 speedup (on the same computer)
Multi-platform : PC, Virtual Reality (VRVOLC...), University Clermont Auvergne (UCA) mesocentre SMP supercomputer, University of Columbia VICTOR platform...
Read any raster ASCII Esri asc file (*.asc)
OpenMP, Optimization (use fastmath, use float, facilitate compiler vectorization, use MULT instead of DIV...)
Write TIFF files and/or an binary height matrix
