Save data from whole patch at each time step

Tscar · April 26, 2016, 02:11

Hello,
I need to save data at each time step the solver computes and I need to do it for whole patch (or at least for defined line). Does anyone know how to do it?
Solution is probably something similar to a probe, but instead of single point, I would like to specify whole patch.
Thank you.

You want a "surfaces" function object:

Thank you. Could you please post a piece of code that needs to be inserted to contolDict to to write say pressure at whole outlet at each time step? I tried to write something, but I can not seem to make it wok.

You can find such examples in the tutorial folder of OpenFOAM.
