Good morning, I should simulate the motion of a particle, which is hit by a flow that drags it, inside a wind tunnel using a dynamic mesh. Is it possible to do this with Ansys Fluent, and if so, how can I do it?

Assuming it doesn't need to hit anything then you're looking at the 6DOF solver in moving/deforming mesh. If the particle is very small then DPM or adding Ansys Rocky to the Fluent solver may be more efficient.

I recommend utilizing Ansys Rocky in conjunction with Fluent for your application. Depending on the extent to which particles affect the airflow, you have the option to select either 1-way coupling or 2-way coupling. Here is an example of airflow moving particles: https://youtu.be/7UP7D54J2wE.
