Create nu field in multiphase solver -interFoam

renos · July 30, 2021, 08:30

Hello,

I would like to create a kinematic viscosity field for interFoam solver and save the values of the field in a text.

How I can create this type of fields?

Any idea?

Thanks in advance,

Renos

Depends what you are trying to do. If you want to calculate it once and dump it, there are pre/post processing tools that will do that (setFields for example). There's also function objects that you can place usually in your fvSolution dict that can calculate it on demand. If you want to do a lot of things you can hack open the solver and go to createFields.H and create an IOObject, which makes the field available at all times including runtime, and recompile the solver.
