Hello,

I've been trying to run the planeWall2D tutorial in OpenFOAM 4.1 in order to understand how to set up a chtMultiRegionSimpleFoam case. However, there seems to be a problem running the case when the solver chtMultiRegionSimpleFoam is invoked.

This is the error from the chtMultiRegionSimpleFoam log:

--> FOAM FATAL ERROR: 
Unknown Function1 type uniform for Function1 meanValue

Valid Function1 types are:

7
(
constant
csvFile
polynomial
sine
square
table
tableFile
)



    From function static Foam::autoPtr<Foam::Function1<Type> > Foam::Function1<Type>::New(const Foam::word&, const Foam::dictionary&) [with Type = double]
    in file /home/ubuntu/OpenFOAM/OpenFOAM-4.1/src/OpenFOAM/lnInclude/Function1New.C at line 60.

FOAM exiting

How could I go about solving this issue?

Thanks you!

Edit: other chtMultiRegionSimpleFoam cases (like the ones provided in the tutorials that come with OpenFOAM) do run without this error.

Found the problem! It was in the boundary condition definition for p_rgh.

At least in my build, this boundary condition is not supported/gives errors:

        type            fixedMean;
        value           uniform 100000;
        meanValue       uniform 100000;

Hi Marc,

i have the exact same error. The case still does not work when i change the boundary conditions you mentioned above. How exactly did you change the bc?

Hi Archy,

Well basically you can:

1. 1. Write the proposed BC correctly:
      In system/*Air/changeDictionaryDict instead of:
      

              rightLet
              {
                  type            fixedMean;
                  meanValue uniform 1e5;
                  value           uniform 1e5;
              }

      Write:
      
      

              rightLet
              {
                  type            fixedMean;
                  meanValue       1e5;
                  value           uniform 1e5;
              }

      Which works for me
   2. Or you can define another boundary condition such as:
      
      

          rightLet
          {
              type            fixedValue;
              value           $internalField;
          }

      Or explore other options. This pdf has a nice explanation of different BC which might be useful.
