This page provides information on the Thinking Particles Phoenix FD Birth operator.

## **Overview**

---

<span style="color: #202124">The Phoenix FD Thinking Particles operators allow you to create and modify particles based on the Phoenix fluid simulation.</span>

<span style="color: #202124">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 simulation where the Temperature is above a certain threshold, there is no Smoke, or the Speed is very high.</span>

 

## **Inputs**

## **Outputs**

---

***Born Particle** [ particle ] – The particles born from the TP Birth operator.

***Particle Frame Counter** [ integer ] – The amount of particles born from the TP Birth operator on the current frame.

***Particle Animation Counter** [ integer ] – The amount of particles born from the TP Birth operator during the current thinkingParticles simulation.

> Macro (ui-text-box)
> 
> "*" denotes an array output - multiple values will be output during a single evaluation of the TP Birth operator.
