I'm currently running a melt convection simulation in ANSYS CFX, where the melt is modeled as a spherical domain with a temperature boundary condition applied at the surface. I'm planning to analyze the dopant distribution under natural convection and later compare it with forced convection.
To introduce the dopant, I’m considering three methods:

1. Injecting the dopant directly into the melt stream using an additional variable.
2. Creating a subdomain that acts as a dopant source.
3. Particle Tracking (not sure about it )

Which method is generally more effective for accurately modeling the dopant behavior in this scenario? I want to see how the dopant is dispersed/ distributed in melt.


What’s the best way to visualize and quantify the dopant distribution in CFX-Post?
