XFlow: Fluid simulation tool

I’ve just come across XFlow, from NextLimit, which is an accurate fluid simulation tool. It uses a particle based method, instead of a computational grid that are used in other Computational Fluid Dynamics (CFD) tools.The interesting part of this tool is that they have explored other fields, where CFD can be applied to. As they use a particle based method, it is well suited for applying to simulation for complex systems. Examples include:1. Traffic Simulation2. Cell Simulation3. Crowd SimulationFor the crowd simulation application, the particles can represent the pedestrians in different conditions, which can then be applied to scenarios such as emergency evacuation.
