GFS

About GFS.

The Gerris Flow Solver (GFS) is a free software program for the solution of the partial differential equations describing fluid flow. A brief summary of its main (current) features:

• Solves the time-dependent incompressible variable-density Euler, Stokes or Navier-Stokes equations
• Adaptive mesh refinement: the resolution is adapted dynamically to the features of the flow
• Entirely automatic mesh generation in complex geometries
• Second-order in space and time
• Unlimited number of advected/diffused passive tracers
• Flexible specification of additional source terms
• Portable parallel support using the MPI library
• Volume of Fluid advection scheme for interfacial flows

Using GFS on Stallo:

GFS is installed under:

/global/apps/gfs/<release-date>/

To be able to use GFS you must load the GFS module on Stallo:

module load gfs

You must run this command before you try to link you application with this library.
And you may have to add this command after the PBS-stuff and before the executable stuff in your job script.
