CFD Online Discussion Forums - How to engineFoam?

Hello. I would like use engineFoam solver for my own case.

Additional info:
CAELinux 2013 64bit
I uninstall openfoam211 and install openfoam221 because kivaTest and entire engineFoam solver doesn't work due to well known bug.
Salome-meca 6.6

At first I create my own geometry of combustion chamber. Then I mesh it structurally. Centre part is divided cylinder.

Dimensions of geometry:
Diameter = 38mm
Heigh = c.a. 55mm

I create groups of faces for liner, piston and cylinderHead and export mesh to unv. (Also I create group of volumes containing all 76500hexahedrons. I don't know if this is necessary? Or maybe I shouldn't create it? )

Then I create my own case folder tree.
I run ideasUnvToFoam.
Because my geometry is in millimetre I run
transformPoints -scale '(0.001 0.001 0.001)'

I'm not really sure if I run checkMesh and engineCompRatio as next step. Is it important to solver?

Anyway I run them in one of my others attempts. Results:
ideasUnvToFoam: http://wklejto.pl/238890
transformPoints: http://wklejto.pl/238891
checkMesh: http://wklejto.pl/238893
engineCompRatio: http://wklejto.pl/238892

Are those results really ok?

Ok, Now I edit a little bit files from kivaTest (I based my case on kivaTest).
In file engineGeometry I set parameters of conRodLenght, bore, stroke, rpm. I remove clearance because I can't find what it is but it looks like this settings is optional? Anyway I would like to know what it is...
In file combustionProperties I set location ignition inside my geometry.
In file controlDict I set deltaT to 0.0625.
In file boundaries I set type as wall instead of patch.

I run engineFoam.
It solve my case to -25 CA and then temperature blows up (randomly for example from -3e27 to 3e54). (core dumped)

So I decide to edit my case again and start from -25 CA:
In file controlDict I set deltaT to 0.001 and startTime -25
In file fvSolution I set nCorrectors to 6 and nonOrthogonalCorrectors to 3

I run engneFoam.
It solve my case to -20 CA and then termperature and pressure blows up. Here is end of logfile:

At the end I run checkMesh for -20 geometry:

I wonder if
Max aspect ratio = 109.998

is really ok?

I hope that somebody could help me a little bit with this. I would like to became openFoam expert some day.

Greetings and thanks for reading!
