Bruno Chareyre posted a new comment: Hi, Just to summarize a few ideas after a discussion with Robert: - the duplicated "setPositionsBuffer()" in DFN was definitely an experimental hack and it is unsafe to keep relying on this. - removing this duplicate would let two-way-coupling work as it should (since the inherited setPositionsBuffer is not conditional). What is really needed is 1/ a way to update permeability data based on cracks extension and aperture and, 2/ to rebuild the permeability matrix after that. To be sure no remeshing will occur it is enough to set FlowEngine's meshUpdateInterval and defTolerance negative. Further: if permeability is only updated in the cracks (not in intact matrix) some performance could be gained by using cholmod update/downdate features (cholmod_updown), which updates factorization without going through the complete Cholesky algorithm (even changing the size of the problem for advancing cracks seems to be possible).
