Using SolutionParameter component to update p_rgh

1

When I try to use the Butterfly Solution Parameter component to update p_rgh condition, it shows error message:

  1. Solution exception:p_rgh is not a valid OpenFOAM dictionary file. Try one of the files below:
    epsilon
    k
    nut
    p
    U
    T
    turbulenceProperties
    transportProperties
    blockMeshDict
    controlDict
    fvSchemes
    fvSolution
    snappyHexMeshDict
    probes.

Anybody who knows which python codes should I modify? I tried editing the solution.py but nothing changed. Thank you very much in advance!
