Hello to everyone.

I try to solve a two stroke engine case with a sliding interface, combustion and a moving mesh.
For a test case I use a quiet simple geometry of a cylinder and an inlet.

The solver is based on the sonicTurbDyMFoam. I can start the solver, but it works only until the point, where the moving mesh come to the inlet.
At this point the solver should decouple the sliding interface but the solver breake off. And shows:

--> FOAM FATAL ERROR : attempt to use janafThermo<equationofstate> out of temperature range 200 -> 6000; T = 0

From function janafThermo<equationofstate>::checkT(const scalar T) const
in file /usr2/tmp/cmende/OpenFOAM/OpenFOAM-1.4.1-dev/src/thermophysicalModels/specie/lnI nclude/janafThermoI.H at line 73.
FOAM aborting

I think the problem is based in the creating the wall boundary ...
As a matter of a fact the boundary after detaching gets a false temperature value. I searched the whole code, but I can't find the piece where it updates the boundary values.

Can anybody help me.

Have a nice day.

Hi Sebastian,

were you able to get your solver running? I am currently trying to set up a case with sonicTurbDymEngineFoam and can't seem to set the case up. I have found some examples with other solvers but they don't seem to help me much. Maybe you could share some of your gained experience? I would really appreciate it, I still haven't figured out how to set up the dictionaries to get the case running :S
