ishan_ae is on a distinguished road
I am sampling a surface and the associated data after every 1000 time steps.

Is there any setting through which I can sample at every time step but keep only 20 files ? This is requirement is similar to what we can do with time directories through the "purgeWrite" keyword.

I want to monitor my simulation through this approach.

Is it possible to do something like this within OpenFOAM ?
