Hello everyone,
I am doing an school project in which i need to simulate an high speed fluid (1000m/s) entering a venturi tube. I want to simulate the pressure and speed in the venturi tube. I am doing this in the online-simulator Simscale which uses openFoam. At this high-speed density changes cannot be ignored, so i choose compressible in the options panel. Evertime I try to run the simulation I get the following error:

mpirun has exited due to process rank 3 with on
node exiting improperly. There are two reasons this could occur:
1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.
2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"
This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

I think the main problems lies with the:

[17] incompatible dimensions for operation
[U[0 1 -2 0 0 0 0] ] + [U[1 -2 -2 0 0 0 0] ]

I am however, a newbie to the program, so I don't know how to fix this.
Does anyone have an idea?
Kind-regards

Do you by any chance initialize the solution with the potential flow? If yes, then just uncheck it and you are good to go.

Thanks to this, the error has dissappeared.
