Parameters for Massed Particle Traces.

If these parameters are specified in the ParticleTraceGroup.massedParticleParameters property, the particle trace will be computed based on a massed particle formulation using the given parameters.

To compute normal steam lines (massless particles), set ParticleTraceGroup.massedParticleParameters to undefined (this is the default setting).


The constant fluid density to use if the fluidDensityResultId is not set (-1)

Particle density

ID of scalar result for fluid density

ID of scalar result for fluid molecular viscosity

Gravity (e.g. <0,0,-9.81> for nomal earth gravity if in SI system)
