Hello everyone,

greetings from Germany. I'm attempting to simulate a simple rectangular object floating with 6 DoF in a 2-D tank with laminar flow. However, even when I'm not trying to calculate any forces on the object, still I'm getting the following error:

--> FOAM FATAL IO ERROR:
keyword nu is undefined in dictionary "/home/stripathi/OpenFOAM/stripathi-2.1.1/run/tutorials/multiphase/interDyMFoam/ras/floatingBox/constant/transportProperties"

file: /home/stripathi/OpenFOAM/stripathi-2.1.1/run/tutorials/multiphase/interDyMFoam/ras/floatingBox/constant/transportProperties from line 20 to line 32.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 400.

FOAM exiting

I have gone through the extensive discussions on this topic on the forums here and somebody suggested to change the following line in forces.C

dimensionedScalar nu(transportProperties.lookup("nu"));

to

dimensionedScalar nu(transportProperties.lookupEntry("phase1").dict( ).lookup("nu"));

I have tried that too but to no avail. I don't seem to understand why the solver needs the value of nu when I'm not calculating any forces. Please help.

If necessary, I'll be happy to share my entire case files.

Thanks,
Sagun
