i'm running a simulation of a rocket nozzle using openFoam since the Fluent license expired. I'm very new to openFoam, so i have almost no idea why this error happens. The simulation was based on sonicFoam laminar tutorial.

Here's the case file: https://www.dropbox.com/s/lzgbwv7yce...sonic.zip?dl=0
