Hi
I try to set up an engine mesh with canted valves and piston layering. Therefore, I chose the thobois class in the engineTopoChangerMesh class. I already succeed in running a case with the accordionEngineMesh class but with thobois class, i got the following error. I am running it on 1.6-ext. Quote:
Remark: I had to change the addAttachDetachFacesThoboisMesh.H file with addAttachDetachFacesAccordionEngineMesh.H. Otherwise I couldn t create the meshModifiers. The thoboisMesh class looks very similar to the accordionEngineMesh class, but with piston layer. Peter |

I solved the problem.
I have changed in the motionU file the boundary conditions for the piston to componentMixed. Does anyone knows what is meant by this bc§? I don t understand this boundary conditon. How to set it up? Anyway the case isn t still working properly. Peter |

Hi Peter,
I am trying now to do the same, tilted valves and piston layering. I am working on the thobois class but started also with the accordionEngine class following your posts, but I can't get it to work. What changes did u need to do? All the point, face and cell Zones for moving and static parts are created, but I am quite confused cause they dont get written as mesh modifiers in any way, so don't know if the code is complete or not :S any ideas? would appreciate it |

Hello Peter
I am doing PhD in CFD in Mechanical Eng. Department, I am trying to simulate 4 stroke diesel engine with flat head and canted valves around 4 degree. I am trying to use thobois class in OpenFoam Ext 3.1 Am I using right class? I think you have successfully implemented this class and i think no would better know about this class than you. I have some queries about some keywords definitions? detachFaces movingPoints movingInternalPoints staticCells movingCells staticPointsName any demo case or any kind of information would be really helpful. Thanks Amrinder Singh |
