This Computation Fluid Dynamic (CFD) model of a sugar beet clamp has been developed using the OpenFOAM open source software. The table below gives links to posts that describe the development of the model
The github repository for these models are public. You need an OpenFOAM installation to run the model, ParaView to inspect the results, and a lot of knowledge to modify the model…
The physical model is fairly idealised, but also has a fairly good resolution and is built on some sound experimental data.
TABLE: Steps in the model development, including solver, case files, tags of the important features, and links to related blog posts.
