This time I bring a new method to mix fluids with using Graphs in RealFlow.
Thanks to the help of Alex Ribao from Next Limit I would like to share this graph to mix two fluids using the temperature channel of the fluids. This idea is not mine I took it from Thomas Schlick https://rftoolfactory.wordpress.com/2015/01/21/fluid-blending/, but instead of using py script we use Graphs that is faster in calculations in some cases.
This a pretty simple scene of two fluids, yo can set different properties, as viscosity, density, etc. Even using this method I think you could do it more complex and mix properties between fluids.
But firstly I would like to prevent you that exist some tricky things in this method that we have been aware. By default liquid emitters have not temperature channel so to create them we have to switch them to Gas and we should set the temperature to 0 for one and to 1 for the other and switch again to Liquid, so we had the channels created.
Once done this we only need to load the Graph to the stepPre slot in the Simulation Graph.
The graph is quite simple, the particles from both emitters are loaded and read positions and temperatures, then through creating a distance field the particles transfer the temperatures between them and these are updated. The mixed area can be controlled with the CellSize node, although you can add extra control in the rendering process too. For rendering, this time I used Arnold through RenderKit, now I am testing the workflow with Maxwell and will try in VRay too. This are the connections for Arnold.
