Reply To: Checkpointing can’t be used in phaseSeparation2d etc.
Additional field data declared by the descriptor is saved / restored by the super lattice serialization.
Did you call SuperLattice2D::postLoad as in e.g. examples/particles/magneticParticles3d/magneticParticles3d.cpp:591? This is called automatically in our current development version but unfortunately not in the current release.
Depending on the exact code, there may be further obstacles in this particular example – e.g. the initial setup is random and non-reproducible by default. Also average rho in general is computed during collideAndStream and not up-to-date directly after reload.
If you post your adapted code I am happy to assist you further.
