Errors running Caradonna (rotating blade) test case

Gaso · May 28, 2013, 12:28

Hi,

I'm still learning, so probably i'm missing something obvious.

When I try to run the caradonna test case, it shows a lot of points with negative pressure and then start iterations, every iteration says "nan".

The original test case configuration file looked for a mesh file with a slightly different name, so I changed that. Everything else is equal.

Anyone have any idea what may be wrong?

Thank you!!

Hi,

Sorry that you have found some problems with the Caradonna test case. Unfortunately, this configuration file (and mesh) are a bit outdated and, because we have recently changed the periodic boundary conditions, it is unlikely that this case will work with the later versions of the code (2.0+). You might try running this case with version 1.0 of the code.

Apologies and all the best,
Tom
