### *class* RAParticleInlet

Rocky PrePost Scripting wrapper for a single Continuous Injection input.

This wrapper class corresponds to an individual entry under the “Inputs” item on the project’s data tree. Particle inputs can be retrieved from the [`RAStudy`](RAStudy.md#generated.RAStudy) or the [`RAInletsOutletsCollection`](RAInletsOutletsCollection.md#generated.RAInletsOutletsCollection) via:

```python
input_1 = study.GetElement('Continuous Injection 1&gt;')
input_2 = input_collection.GetParticleInput('Continuous Injection 2&gt;')

```

Instances of [`RAParticleInlet`](#generated.RAParticleInlet) comprise two parts: Properties that can be manipulated directly, such as the input’s name and the particle entry point, and the input properties list that describe which particles enter via this input and with each mass flow rate, temperature, etc. This list must be manipulated via the `RAParticleInputPropertiesList` returned by [`GetInputPropertiesList()`](#generated.RAParticleInlet.GetInputPropertiesList).
