Dear Petsc developer team, while learning the ways of the petscFE I came across a curiosity I’d like to point out to you. The Jacobians that are created from the petscFE object seem to have only 0-entries (apart from the obviously empty regions) in examples 12 and 77. That might be due to a limited understanding from my side on how exactly petscFE and the mentioned examples work, but it struck me as unusual.
Thanks in advance, M. Hartig
