Hi,
I am reporting a convergence issue with the omega transport equation of the k-ω SST turbulence model in Nalu-Wind. I’ve attached non-linear residual plots for NASA’s canonical case: the subsoni…

In the Lagrangian action of an undamped simple harmonic oscillator (#34), one can easily find the first integral
$$\frac{1}{2} m \dot x^2 + \frac{1}{2} m \omega^2 x^2 \equiv E \eqqcolon \frac{1}{2} m…

### Description
In some cases (see e.g. #7734) derivatives are involved in nonlinear strong components. If not solved with the appropriate precision, they may fool the ODE solvers's error control m…
