Openfoam bodyforce

skbake94 · February 21, 2024, 08:49

Hi guys, I am doing a research in a different field but I wanted to connect my research topic to CFD so I recently started learning to use openFoam. I have been trying to reproduce a simulation from a journal and have figured out about most of the settings of the simulation I want to do but this simulation has sin(4y) to x direction as a source term. How can I implement this bodyforce into either simpleFoam or pimpleFoam?

Thanks,

Hello,
You will need to use fvOptions

And probably for the type of force that you have mentioned (a sinusoidal forcing varying spatially), this will be useful to you:

See the description on implementation here:
https://www.openfoam.com/documentati...8H_source.html

Finally, I also think this thread might be of help
How to add a body force to a momentum equation
And for an example, see this answer in the same thread

Hope this serves as a starting point for you

Good luck!
