Export forces at each nodes with OpenFoam

Santos-Dumont · February 19, 2014, 05:29

Hi everyone,

Does anyone know if it possible to export the nodal forces with OpenFoam ?

To be more specific what I'm after is a file with for each nodes of a patch the values of X, Y, Z, Fx, Fy, Fz

These values must be somewhere in the code as the patch forces output is surely the sum of the force applied on each nodes or faces of the patch...

What I want to do is use these values in a custom made structural software.

Thanks
Charles

I think you want to deal with Function Objects

hope I pointed into the right direction

Hi, Charles,

Did you find a way to achieve that?

Best regards,
