This scene demonstrates how to set up a coffee scene using Phoenix. The Liquid Source for the coffee emission is using a Discharge modifier that modifies the Outgoing Velocity on the negative Normal Z. This way the liquid is emitted only by the parts of the emitter that are facing downwards.
The scene is built in real world scale and the coffee cup is around 7 cm tall. The Phoenix Simulator is using a Scene Scale of 10 and the Steps per frame are set to 15 in order to account for the fast movement of the liquid.
In the Foam settings a dummy box geometry, that is non-solid and non-renderable, is used as a Birth Volume in order for the foam particles to be born only near the bottom of the coffee cup. The Foam Volume is set to 100 which is a balanced value, in order for the foam to stack up in a thick layer on top of the liquid.
A Voxel Shader is used to read the Speed channel of the liquid and render it as smoke. The faster the liquid is moving the denser the smoke will be. This emulates foam emission of tiny foam particles when the liquid is moving fast enough without having to simulate millions of foam particles. Then the liquid is used as a Cutter Geometry for the smoke so that only the parts that are inside of the liquid are rendered.
Software used: Phoenix 5.10.00 Official Release, V-Ray 6, hotfix 3 Official Release, 3ds Max 2018

This scene demonstrates how to set up a rocket launch scene using Phoenix. A Fire Source in Volume Inject mode is used for the smoke emission from the rocket and the boosters. Another two Fire Sources in Volume Brush mode are used to change the RGB color of the smoke near the ground to give it more variation. Since the scene has a lot of geometry and we wish only a few parts of it to interact with the simulation, the Scene Interaction is set to Include list and only the objects relevant to the simulation are picked. For the rendering the Smoke Scattering is set to Ray-traced in order to get more realistic scattering of the light through the smoke. The Phase Function for the smoke is set to 0.7 so that the light can scatter more and give the lighter smoke steam appearance. The scene contains a primitive called "Blocker" which is a Solid Object until frame Frame 74 and holds the smoke generated by the Boosters below the Launchpad, after frame Frame 75 the Blocker is set to a Non-Solid Object and the smoke can start travel upwards.
The attached lower resolution scene is using example scene with higher resolution has a starting Grid Resolutionof 1.7 of 12 million cells, Voxel Sizeof of 0.397m and the 203m and Adaptive Grid is set set to Smoke, so the Grid will automatically expand when it's needed and reaches 800 million cells in . The Grid Resolution reaches 1.4 billion cells in its final stage at at Frame 300.
The attached higher resolution scene is using example scene with lower resolution has a starting Grid Resolution of 47 1.7 million cells, Voxel Size of 0.13m and the Adaptive Grid is set 397m and Adaptive Grid set to Smoke, so the Grid will automatically expand when it's needed and reaches 23 billion cells in . The Grid Resolution reaches 413 million cells in its final stage at Frame 300.
The examples example videos below demonstrate the results with two Grid Resolutions scaled to 23 1.4 billion cells and 800 413 million cells.
