Hi, Foamers!!

I have some trouble in Diesel engine simulation in OpenFOAM.

I made "my sector mesh" by converting from KIVA3V to OpenFOAM and got "control", "system" folder files from dieselFOAM tutorial case. (control/enginegeometry file comes from engineFOAM tutorial case)

I used dieselEngineFOAM solver that provided by OpenFOAM 1.5.x

Finally, I can see moving mesh and diesel spray injection in my mesh!!

But........."Pressure" does not changing!!
Pressure always keep staying for both motoring & injecting conditon
(i.e initial condition for p = 100000 at -180
after -60 degree "p" also 100000)


How can I solve this problem......

belows are my input file list
/-180/epsilon, k, N2, O2, p, spray, T, U and Ydefault

/chemkin/chem.inp

/constant/chemistryProperties, combustionProperties, engineGeometry
enviromentalProperties, injectorProperties, RASproperties, sprayProperties
thermophysicalProperties

/system/controlDict, fvSchemes and fvSolution

Hi Karam,

Did you manage to solve the pressure problem? I am using sonicTurbDyMEngineFoam and I observe the same thing!! pressure is not changing :S I am running out of ideas, maybe you could tell me what the problem and solution was in your case??
