Hello,
In a pimpleDyMFoam rotor simulation, after running seamlessly for 2.3 seconds of simulation time, with Courant number within the limits, the following error is observed:

--> FOAM FATAL IO ERROR: 
wrong token type - expected Scalar, found on line 0 the word 'nan'

file: /media/mslab02/space/STL_Trials/Deviation_0_1/Angle_8/system/data.solverPerformance.U at line 0.

    From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::doubleScalar&)
    in file lnInclude/Scalar.C at line 93.

FOAM exiting

I understand that the 'nan' error happens because of some major issue, such as boundary conditions etc. but the same problem, with a different rotor geometry worked perfectly.
Is it the geometry that is causing problems? How do I solve this problem? Any guidance would be heavily appreciated.

Thank you.

Hey Sorabh. I'm encountering the same problem for my rotordisk simulations using SimpleFOAM. Were you able to resolve your situation?
