A GfsForceDrag is one of the type of forces that can be exerted on GfsParticulate discrete mass-particles in the particulates module. As its name suggests the drag force opposes the slip velocity.

The syntax in parameter files is:

 [ GfsForceCoeff ]

which only occurs as part of a GfsParticleList and within which it looks like:

 GfsParticleList { ... } GfsParticulate { ... } { 
   ...
   GfsForceDrag Cd 
   ...
 }

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

For developers the object hierarchy for GfsForceDrag is:

• GtsSListContainee
  • GfsParticleForce
    • GfsForceCoeff
      • GfsForceDrag
