Hi,

I am currently working on water jets. I want to calculate the force on a wall.
Hence, I'm only interested in the contribution of the water phase.

I already read multiple posts about this topic, but I am not sure if this tool works for my case.

Wall forces in interFoam

I found a nice way to do it in Paraview, but I would like to calculate the force in every tilmestep.

https://www.simscale.com/docs/conten...esMoments.html

The forces functionObject seems to calculate it in a different way and it seems that it's something like a force density?

How should I declare rhoInf to get realistic results?

Thanks!

Hi

So did you get anywhere yet ?

I also found this post: Force calculation in multiphase simulations
here they adapt the existing force calculation function object in order to fit for the interFoam solver. I heaven't dived into it yet, but as I understood it, this would only be applicable for laminar cases. But I don't think your case is laminar, is it?

Cheers!
Bram
