    Hello Developers,
    I am setting the physical kinematic viscosity of water as 8.917e-7 m2/s. After compiling and running the code, it doesn’t output any results.

    UnitConverterFromResolutionAndRelaxationTime<T, DESCRIPTOR> const converter(
    int {N}, // resolution: number of voxels per charPhysL
    (T) 1.0,//0.8 // latticeRelaxationTime: relaxation time, have to be greater than 0.5!
    (T) ly, // charPhysLength: reference length of simulation geometry
    (T) 1e-7, // charPhysVelocity: maximal/highest expected velocity during simulation in __m / s__
    (T) 8.917e-7,//1./Re, // physViscosity: physical kinematic viscosity in __m^2 / s__
    (T) 1000.0 // physDensity: physical density in __kg / m^3__
    );

    I would really appreciate your help in this matter.

    Thank you.

    Yours sincerely,

    Abhijeet

    This problem is fixed. I had to change the lattice relaxation time. All is good now
