--> FOAM FATAL ERROR: NO_READ specified for read-constructor of object nuTilda of class IOobject

[lkampoli]

Hello, thank you very much for this work, it is very helpful.
I run through all the steps successfully, then I execute simpleFoam_ML from the Testing directory and I obtain this fatal error (attached).
May you have some hint?

--> FOAM FATAL ERROR:
NO_READ specified for read-constructor of object nuTilda of class IOobject

Kind regards,

Hi Lorenzo - I see that you are using Version: v1706 - I have not tested this repo with it. Have you isolated the error within the new turbulence model class? Which line does it crash?

[lkampoli]

Hello, indeed, I confirm that by running with OF-5 I successfully completed the simulations without encountering any problem. Anyway, it is interesting to understand why OF-v1706 fails. I will investigate further ...

Hello, sorry I reopened this issue just for an update.
I noticed that by using READ_IF_PRESENT instead of NO_READ as below in /OF_Model/ML_SA_CG.C the simulation runs also on OF-v1706. Now I'm wondering whether this would alter the computation ... is it still using TF prediction?
Thank you

Wow @lkampoli ! Great catch. No - this should not affect the prediction because the SA model (which computes nuTilda) is switched off here.
