Summary0000887: Conservativity Problem of AMI-Interpolation
DescriptionTestcase evaluation has shown conservativity issues for AMI-Interfaces. Interfaces are conservative with respect to their neighbour but loose mass compared to inlet/outlet. Our suspicion is that the matrix-update in the fvPatchField / GAMGInterfaceField does not fullfil conservativity.
Computation of fluxes with the interpolation may be globally conservative but using averaged fluxes together with weights seams to lead to conservativity failure. We think it would be better to use local variables together with the weights to compute the fluxes there instead of using the already averaged fluxes.
Steps To ReproduceIf you need a testcase please send me an email where i can put it. It exceeds the 2MB limit.
