Hi everyone!
My name is Alex and I'm a CFD student, and I need some help to understand why, in the case I will explain, calculations are stuck at iteration 0, so, basically, it doesn't start. I'm analysing an academic case where there is a combustion chamber of a piston, and inside it there is a mix of air and vaporised fuel; then, through different injectors, a new amount of fuel is injected, in order to reach a stoichometric equivalence ratio. I already set everything, from physics to boundary conditions (only walls). What I can not understand is why there are these warnings and the calculation doesn't go on, and is stuck on iteration 0. The warning messages are the follwing: "Assembling H and Cp Look up Tables for 13 species...done! pressure corrections limited on 520 cells in CombChamber pressure corrections limited on 20 cells in CombChamber pressure corrections limited on 2 cells in CombChamber" One of my friends gave me a copy of the file of his own simulation, and I tried to clean the results and restart the simulation: these warnings appear, but then, after a few seconds, it starts calculating and after some iterations they disappear, and the solver goes on. I already checked if all the settings where comparable to my friend's file, and they are. I would like to say in advance thanks so much to everyone that will help me! |

Build a new file based on your friend's file. Launch it. It's a small mistake. |
