Hello all,

Is there a way to only save certain field results during a simulation?

I.e. I would only like to save P and U, and would not like to save the rest of the default parameters. It is taking too much space and I don't even need them.

Is there a way to change controlDict or any other file that would allow this?

I've seen writeRegisteredObject but not quite sure how to use it..anyone?

Thanks!

To write only a few fields, use this in the solver instead of runTime.write() and recompile :

Code:
if (runTime.write())
{
U.write();
p.write();
}
