GfsForceDrag

From Gerris

A GfsForceDrag is one of the type of forces that can be exerted on Lagrangian particles (GfsParticles) part of a GfsParticleList. As its name suggest it sets the drag force acting on a Lagrangian particle.

The syntax for GfsForceDrag as part of the GfsParticleDrag syntax is:

GfsParticleList ... GfsParticle ... { GfsForceDrag Cd }

where Cd is the drag coefficient of the particle (double).

For developers the object hierarchy for GfsForceDrag is:

   * GtsSListContainee
         o GfsParticleForce
               + GfsForceCoeff
                     # GfsForceDrag
