Hi everyone,

I'm new to OpenFOAM and I am modeling a circular pipe using an axi-symmetric mesh for compressible turbulent flow. When I run the case using rhoSimpleFoam I get the following error message:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Create mesh for time = 0


SIMPLE: no convergence criteria found. Calculations will run for 1000 steps.

Reading thermophysical properties

Selecting thermodynamics package hPsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
Reading field U

Reading/calculating face flux field phi

Creating turbulence model

Selecting RAS turbulence model kEpsilon
bounding k, min: 0 max: 1 average: 1
bounding epsilon, min: 0 max: 200 average: 200

I believe the cause of the error is in my boundary conditions, which I have attached, however I am not sure how to proceed from here. Any help that could be offered would be greatly appreciated.
