Overview
The 'Buoyancy' API introduces buoyancy forces to the DEM particles without using a coupling with a CFD solver. There is also an example attached that shows the usage of the API.
Prerequisite: EDEM 2025.0 or above
Usage/Installation Instructions:
- Extract the zip file attached. Copy the 'Buoyancy.dll' from the 'example' folder to the directory of your EDEM simulation.
- Add this model in the 'Particle Body Force' of the Physics section.
- You will need to enter the density value of the fluid, and you can choose which particles you would like to add the buoyancy force to.
- Optionally, you can also choose to define a fluid surface in the form of a plane, and any particles below the surface (based on the direction of gravity) will have a buoyancy force applied to them.
Post-Requisite:
This model only applies buoyancy forces. No aerodynamic forces are incorporated into this attached code. If you wish to add drag or lift models, please choose those models accordingly which are compatible with this current implementation of the buoyancy force.
Release Version: EDEM 2025.0 or above
