Hello Brunos,

For the first time, I am experiencing SigSegV handler error as follows,

I believe its signal segmentation error and something to do with temperature boundary condition. I have attached the boundary condition files. Please help me what cause this error ?

Also courant number for air is zero, how?

Quick notes:

1. Courant No = 0 probably because the initial U field is set to 0.0...

2. This:

   ZN4Foam12compressible56turbulentTemperatureCoupledBaffleMixedFvPatchScalarField12updateCoeffsEv ...
   ZN4Foam17mixedFvPatchFieldIdE8evaluateENS_8UPstream10commsTypesE [0x6b6980c2+0x22]
   ZN4Foam29mixedEnergyFvPatchScalarField12updateCoeffsEv [0x6a30bd43+0xd3]
   

   • It's hard to spot, but the crash is due to something going wrong in a boundary condition mixedEnergy.

3. More specifically, sigSegV usually means that a bad memory access was attempted, resulting in the application crashing. Said crash seems to have been due to something going wrong during mapping between patches....

The words mapped and turbulentTemperatureCoupledBaffleMixed appear in there, which refer to such a mapped patch between regions...

I did not look into the case, since it would take considerable time to do so.

Issue Resolved.

1. Courant number fixed by giving velocity boundary condition instead of Volume flow rate.
2. Turbulent temperature coupled baffle mixed boundary condition was fixed by renumber mesh to all the regions created which synched the mapped wall boundary condition.
