Particle Tracing Module

New Functionality in Version 4.3

• Particle-particle interactions are now supported (see the Rotating Galaxy model for an example).

• Thermophoretic force, magnetophoretic force, and Brownian force are now available in the Particle Tracing for Fluid Flow interface.

• New release mechanisms in velocity space: spherical and hemispherical.

• Secondary particle emission.

• Sticking expressions and coefficients.

• 2D histogram plots.

• Schiller-Naumann drag force option.

• Distribution functions for auxiliary dependent variables.

• Particles are now released on the deformed mesh for rotating machinery cases.

• Grouping of variables for easier results processing.

• New global variables for the sum of masses and the total energy.

• Filter mechanisms for improved visualization of specific types of particles.

• Comet tail plots.

New Models

• Thermophoresis

• Brownian motion

• Rotating galaxy

Backward Compatibility vs. 4.2a

• Selections are now respected in the particle tracing interfaces. You may get different results when you re-run models created using version 4.2a.
