Dyamically changing particle properties?

I am trying to simulate particle flow in a gaseous meidum, and account for changes in particle size due to condensation or evaporation of the carrier vapor. Does anyone know how to dynamically change particle properties (mass, diameter, etc...) based on local conditions such as temperature?

Hi, you can enable the "Compute particle mass" option in the Particle Tracing for Fluid Flow interface, then in the Particle Properties feature enter an expression for the accretion rate. This can be temperature dependent. This will cause the mass (and hence the diameter) of the particles to change during the simulation. If the accretion rate is positive, the mass (and diameter) will increase. If the accretion rate is negative, the mass (and diameter) will decrease.
