Tutorial simpleFoam pipeCyclic
 

Hello everybody,
I'm trying to learn OpenFoam and I'm using CAE linux, I've read the user guide and I'm now trying to work on the simpleFoam pipeCyclic. Firstly I go in the working directory using cd.... them I use blockMesh and I obtain this error message that I don't really understand. Can you explain me this please?
Thanks per advance
Jocelyn

Quick answer: You have to run the script Allrun:
If you edit the script Allrun, you'll see that it creates the file it's referring to.
