Hello everybody,
I am testing simpleEngine tutorial in OF 1.6-ext., but until now without success. I suppose that settings in dynamicMeshDict are not correct. I am using icoDyMEngineFoam solver. Attached you will find my grid and case settings. Thank you! Dalibor |

it is your liftProfilefiles, I had the exact same error and it took me a lot of time to find it. your syntax should be:
( x y x y x y x y x y ) I am also working on OF 1.6-ext trying to set up the simpleEngine case, but with sonicTurbDyMEngineFoam, which uses compressible flow, and am having some troubles with some Temperatures being =0, which causes division by 0 :S so I would be very interested in your progress!! |

Thanks for information. It is correct, the lift profiles were incorrect.
I have also changed settings in fvSchemes and fvSolution files in order to start calculation. But, at about -200CA the calculation is stop due to following error: --> FOAM FATAL ERROR: Error in point ordering: mixed used and unused points at the end of point list. Last used point: 1284 (-0.01 0.0025 0) First unused point: 1285 (-0.01 0.0025 -0.00875) and point 1375 (0.04 0.0025 -0.013125) is used by a live face. Face 1140 4(1218 1375 1386 1219) with points 4((0.04 0.0025 -0.00875) (0.04 0.0025 -0.013125) (0.04 -0.0025 -0.013125) (0.04 -0.0025 -0.00875)) Face 1141 4(1375 1376 1387 1386) with points 4((0.04 0.0025 -0.013125) (0.04 0.0025 -0.0175) (0.04 -0.0025 -0.0175) (0.04 -0.0025 -0.013125)) Done. From function void polyMesh::initMesh() in file meshes/polyMesh/polyMeshInitMesh.C at line 174. FOAM aborting That is not all. ParaFoam cannot read the data, only at -270CA (initial data), so that I cannot see the grid moving process. Do you have any ideas? My next test case will be with sonicTurbDyMEngineFoam solver, because the incompressible solver for IC-engine simulation is not useful. Once again, thanks for your reply. |

oh by the way, I didnt install paraFoam when i installed OF 1.6-ext, so I use paraview 3.8.0, and I was able to open it with it, maybe you could try that

Dear Dalibor ,
Have you found a solution to your problem? I also want to simulate an engine. Regards, Ralph Last edited by RalphS; March 22, 2011 at 11:37. |

ok, i am not quite sure, but i think if you play with the min max cell thickness values and deformAngle, you could solve the problem.
