The Phoenix FD Thinking Particles operators allow you to create and modify particles based on the Phoenix FD fluid Phoenix fluid simulation.

The birth probability is based on the fluid parameters and is determined by the corresponding diagrams. For example, particles can be created only in those areas of the Phoenix FD simulation Phoenix simulation where the Temperature is above a certain threshold, there is no Smoke, or the Speed is very high.

Column width 50%60% Phoenix Simulator | node – – Determines which Simulator will be used to read the fluid data from. Group – Specifies a thinkingParticles Group to place the newly generated particles into. Rate  | rate_type[0], rate_percent – A Sets a multiplier for to the base birth probabilityrate of the operator. Rate (max prt/s) | rate_type[1], rate_per_sec – A multiplier for the birth probabilitySet a limit to the number of particles born per second. Seed | seed – An initial value for the random numbers generator. Lifespan | lifespan – The average lifespan of the generated particles. When Variation (%) is set to 0, all particles have exactly the same lifespan. Variation (%) | lifespan variation – Allows you to vary Varies the lifespan of the generated particles. If set to 100%, the shortest living particles will have a live twice shorter than average, and the longest living particles will have double the average Lifespan. Size | size – The average Size of the generated particles. When Variation (%) is set to 0, all particles have exactly the same Size. Variation (%) | size variation – Allows you to vary Varies the Size of the generated particles. If set to 100%, the smallest particles are two times smaller than average and the largest particles will have double the average Size. Mass | Mass – The average Mass of the generated particles. When Variation (%) is set to 0, all particles have exactly the same Mass. Variation (%) | mass variation – Allows you to vary Varies the Mass of the generated particles. If set to 100%, the lightest particles have Mass two times lower than average and the heaviest particles will have double the average Mass. Combine | combine – The Sets the method used to combine the results of the diagram diagrams for Temperature, Smoke and Speed. Add – The values are added. Multiply – The values are multiplied. Biggest  – The biggest value is selected. Temperature/Smoke/Speed/Fuel | use_t, use_s, use_v, use_f – Diagrams representing the birth density based on each source channel. Reset – Resets the corresponding diagram with its default content. Column width 50%5% Image Removed
