Hallo,
I am running the simualtion for moriyoshihomogeneous in LES model.I want to run the simualtion in dynamicKEqn.But the simualtion is not running.I ma not able to find out the problem.
The problem is shown below.Thanks in advamnce.

We're sorry, but the application crashed and safe stack tracing isn't available in this current implementation of blueCF                                                                                        D-Core patches for OpenFOAM.

Greetings Mahe512,

If possible, please upgrade to blueCFD-Core 2017-1, because stack tracing was made available with that version. That way it should at least give more details on why it crashed.

Best regards,
Bruno
