As part of the R2025x FD03 user assistance, SIMULIA R&D updated a 3DEXPERIENCE example that teaches you how to define and run a simulation that models the airflow around a drone to analyze its aerodynamic performance. In this example, you define a fluid flow simulation using a geometry-based volume definition, and you then model the aerodynamics of the drone. To define, run, and evaluate this simulation, you use the following apps:
- Geometry Idealization Essentials
- Fluid Scenario Creation
- Physics Results Explorer
While completing this example, you learn how to create an exterior volume from an enclosure, for use in a fluid simulation. You then learn how to define a gaseous physics domain for the drone surroundings. To define the airflow direction, you learn how to use a velocity inlet and pressure outlet. You also learn how to utilize a symmetry condition in your model to reduce computational time. After running a simulation that predicts the airflow around the drone, you review the pressure and stress distributions, and compute the lift-to-drag ratio for the drone’s design
You can use what you learn in this example to leverage geometry-based volume definitions in your own fluid flow simulations.
To try this example yourself, see Aerodynamics of a Drone.
Thanks to Jessica JACYNO and @GT for their effort in bringing this example to life!
