Update the fields during the iteration loop
 

Hello,

I am trying to print some fields during simulation in two-phase solver of OpenFOAM 23x.

Therefore, I first define the fields in createFields.H file of the solver. After that I mentioned as function in controlDict file (let's say volAverage value of the field over the whole domain).

Now the problem is that I am getting value of the fields at each time-step but all values are same (like initial values) which is wrong. So it seems, the defined field is not updated each time-step or each iteration.

Can anyone suggest me the right way to record it?

Best regards,
GP
