Hi everyone，I used the pisoFoam to calculate and then use the command 'pisoFoam -postProcess -funcs yPlus' to calculate yPlus.
It works for the time=0 showing

yPlus yPlus write:
    writing object yPlus
    patch wall y+ : min = 2.71465, max = 3.29078, average = 3.01562

However, for the following time step, it showed error.

--> FOAM FATAL ERROR: 

    request for volScalarField yPlus from objectRegistry region0 failed
    available objects of type volScalarField are

5
(
nut
k
nu
p
omega
)


    From function const Type& Foam::objectRegistry::lookupObject(const Foam::word&) const [with Type = Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>]
    in file /home/ubuntu/OpenFOAM/OpenFOAM-6/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 193.

Anyone coud give me a hint on this?Thanks a lot!
