Diverging timestep due to turbulence residuals

It was that message, except max allowed velocity was something like 50000m/s. I am not expecting anything larger than 3m/s though. I’m using a mass inflow, not velocity, could this be the problem? I am not allowed to specify a pure velocity inlet though, but can give optional velocity components below.

I actually made it go longer by fixing the time step, setting a hydrostatic pressure IC, and disabling detect stall. Perhaps I should look further into improving the mesh?
