Hi,
I can store initial residuals as volScalarFields with the functionObject solverInfo with OF v1906. When I sum up all the initial cell residuals the value I get differs from that written in the log file for the variable, e.g. the sum of the volScalarField initialResidual differs from the initial residual for p printed on screen at the same iteration. The dimension of the cell residual is [0 0 0 0 0] so that it seems they are already normalized. Therefore, I guessed their sum over the cells should equal the value reported on screen. Can anyone explain me the reason for the discrepancy? Thank you in advance, Luca Last edited by marluc; October 8, 2019 at 09:01. |
