• Surface Interactions: Erosion/accretion modeling capabilities
• Phase Change Dynamics: Pressure-influenced boiling and temperature-dependent latent heat models
• Particle Interaction Mechanisms: Two-way turbulence coupling, DEM collision modeling, stochastic collision simulation, coalescence, and breakup processes

Particle Introduction Methods

• Injection Configurations: Single-point, grouped, surface-based, and conical release patterns
• Particle Classification Options: Massless tracers, inert particles, liquid droplets, combusting particles, and multi-component formulations

Particle Property Distributions
