hi
I need to simulate a GDI engine in OpenFOAM .
is there anyone who can help me with creating the dynamicMesh

thank you in advance

You can find the necessary files here:

It's probably helpful to use ParaView to see how the patches are defined.

Hello Everyone,

I'm trying to add valves movement to kivatest case. As configuration sample I would like to use simpleEngine case but adopt to tilted valves.

Could somebody please post here files done several years ago by Sandeep for tilted valves (applied in simpleEngine case)?

Links are not availabl anymore. I would very appreciate it.

Best Regards
Grzegorz

Quick answer: This may be very late at this point in time, but see post #64, which I believe has an updated version of the simpleEngine case.

My guess is that "enginePointPatchFields.tgz" is already implemented in foam-extend (3.0 or newer), which would mean that you would no longer need this package.

Hello, 10 years late for that message :D :D

Can you upload the file which explains the different elements in verticalValve and other types of engine topo changers again? because it seems to have been lost. I hope this message finds you well.
