The instructions on this page guide you through the process of using Phoenix's Variable Viscosity capabilities in order to simulate molten lava or metal cooling and hardening over a period of time.
The Download button below provides you with an archive containing the scene files.
Enable Phoenix Simulator -> Liquid -> Wetting. When Wetting is enabled, Phoenix generates another set of particles called WetMap particles. Those particles are created at the point of contact between the liquid and the scene geometry and can be used to drive shaders (through a Phoenix Particle Texture) or specify where the liquid should try to adhere to. You can disable Wetting for a specific object in your scene from its Phoenix FD Extra Attributes.
Set Sticky Liquid to 0.1. The lava will now try to adhere to the rocks.
