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

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.

Hi Dalibor

I have a same error for engine simulation...

have you overcome this problem yet?
what is the origin of this error?

I appreciate any help from you.

Thanks and best regards,
