Default Simulation running but no fluid flow when using paraFoam

George2105 is on a distinguished road
Hey folks,

I am modelling a de leval nozzle into a box with a work-piece inside which is simulated by structuring walls inside the box. I have already run simulations without the work-piece which worked fine. I've kept all my BCs the same, all that has changed is the blockMeshDict file. However, the simulation runs fine but when viewing the solution in paraFoam, it shows that the fluid is not moving. I have changed the BCs where I think I may have been wrong and nothing has worked. No errors occur when running the simulation and being relatively new to OpenFOAM, cannot understand why this problem is occurring. I'll include my blockMeshDict and 0/ files below as well as uploading a .tar.gz folder with all of my files in.

Many thanks in advance,
George.
