engineFoam new mesh problem
I run tutorial kivaTest case without fail.
I want to increase compression ratio value, like diesel engine, about 20. I converted existent kiva mesh (otape17) to OpenFoam mesh(polymesh) with kivaToFoam command. It is ok no problem. Then i converted OpenFoam mesh(polymesh) to a Fluent mesh(*.msh) with foamMeshToFluent command. It is ok no problem. I deleted polyMesh folder which in constant folder. This time I converted Fluent mesh(*.msh) to OpenFoam mesh(polymesh) to a by fluent3DMeshToFoam command. It is ok no problem. I execute engineFoam command. it runs without problem. Code:
kiva mesh ---->> OpenFoam mesh ---->> Fluent Mesh Code:
New Fluent Mesh ---->> New OpenFoam mesh xxxx engineFoam Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // In kivaToFoam command this problem solved by "Transfered xx faces from liner region to cylinder head" Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // /opt/openfoam201/applications/utilities/mesh/conversion/kivaToFoam/readKivaGrid.H Code:
// Transfer liner faces that are above the minimum cylinder-head z height Thanks in advance. |
I used checkMesh command now. The output is below.

Then now engineFoam is working. I am really shame on myself. :rolleyes: |
Good Experience!
Thanks for your sharing. |
Hi ayhan515,
thanks for your shearing. how we can figure the volume of default geometry out and then know the compression ratio and clearance volume in kivaTest ? thanks in advance. |

hi ayhan515,
I appreciate u. yes ,I did ,but unfortunately I don't have any idea. I have some question . would you mind helping me? 1) I want to run the bore*stroke=76*66 in different compression ratio e.g.,12 and 20. How can i create this C.R ? 2) When i run bore*stroke = 86*86 for KivaTest ,it runs until -5 not 60 . what's the reason? thanks in advance. |
