## Question
Hello everyone,
I'm currently trying to reuse the multigrid hierarchy for subsequent linear solver calls, e.g. build the preconditioner once per time step and not for every nonlinear N…

**Describe the bug**
a primal and adjoint restart with multigrid will not produce the correct residuals for turbulence.
**To Reproduce**
Use the restart validation tutorial for species transport.…
