ngbidi New Member Join Date: Mar 2022 Posts: 6 Rep Power: 4	Hi Foamers, is there a way to get the second time derivative on a patch? I would like to calculate the second time derivative for the temperature. So far, I know how to calculate the second time derivative for the whole field with fvm::d2dt2. But I get a fvMatrix and I don't know how to continue with that. Thanks in advance.
