IDDES model #60

Closed jr144393 closed 4 months ago

jr144393 commented 4 months ago

I am interested in utilizing the IDDES model. However, upon its use, I receive the following error:

Caught signal 8 (Floating point exception: floating-point divide by zero)

Other turbulence models with the same case is running, but this one does not. Can someone assist me with the use of this model?

Hi jr,

Could you try compiling the code in FLAVOUR=debug mode and posting the resulting output in this thread?

Also, what kind of case are you running? IDDES is an unusual turbulence model and requires some pretty involved changes to the numerics to get it to work properly.

Nick,

Certainly. I will try this out today and post it here. The case is a simple flat plate, and it was just to test the IDDES for something similar to my case (and to see if I could invoke it properly).

I will close this for now, time has prohibited investigating this further.
