Hi is there a way to use a modified set of data for the convergence criteria (for a serial-implicit scheme). This is a Fluid-Structure interaction between openfoam and a home developed c code, that involves a rigid body. I want to use a convergence on a function of ‘Forces’ or a small number of elements of the Forces vector.
Apologies if this has been asked before.
You could use the actions feature to modify the data, but I am not sure if the output can be used for the convergence checks (this is a feature I have no experience with).
Thank you @Makis , that sounds like a very interesting feature.
