VolcFlow-C : Volcanic flow simulation in C (one-fluid version)

Rewriting in C language, optimization and integrability in various platforms like virtual reality from VolcFlow MatLab Numerical Model one-fluid version.
  • 2.5 speedup (on the same computer)
  • Multi-platform : PC, Virtual Reality (VRVOLC...), UCA mesocentre SMP supercomputer...
  • 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

The freeware version (Windows 10...) is freely available :
- Standalone version (usable with Virtual Reality) : with rheological parameters into a file and source defined by a disk wit (x,y) center of a pixel on the and (r) radius =>Ask for the package<=
- Standalone version : with rheological parameters and source condition into files =>Ask for the package<=
- VR with several sources (soon)
- Web interface to compute at UCA mesocentre SMP supercomputer (next)
