I have checked the case. I have a bad news if you use Foundation variant of OpenFOAM (like of9 or etc…)
There is no any tutorial which is called sonicFoam.. (OMG!!!) You can see below
As I said that I have been using ESI-variant of OpenFOAM around for 10 years and you can see in the below the solver of compressible flow which also includes the sonicFoam.
So, it is not your fault…
Please try to switch to ESI-variant of OpenFOAM.
