simpleSRFfoam : request for volVectorField U
 
Hi everybody

I try to model a rotor in an open stream, using simpleSRFoam.

The solvers returns :
Code:

--> FOAM FATAL ERROR:
    request for volVectorField U from objectRegistry region0 failed
    available objects of type volVectorField are
1
(
Urel
)
    From function objectRegistry::lookupObject<Type>(const word&) const
    in file /home/nous/OpenFOAM/OpenFOAM-1.7.1/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 139.

In folder /0, there is a file Urel as follow :
Code:

internalField  uniform (10 0 0);
boundaryField
{
    inlet         
    {
        type            fixedValue;
        inletValue      uniform (10 0 0);
        relative        no;
        value          uniform (10 0 0);
    }
    outlet         
    {
        type            freestream;
        freestreamValue uniform (10 0 0);
    }
    rotor     
    {
        type            SRFVelocity;
        inletValue      uniform (0 0 0);
        relative        yes;
        value          uniform (0 0 0);
    }
    cyclic
    {
        type            cyclic;
    }
}

In /system, fvSolution contains :
Code:

    Urel
    {
        solver          PBiCG;
        preconditioner  DILU;
        tolerance      1e-05;
        relTol          0.1;
    }

I'm sticked. Who might help me ?

Thanks in advance

[solved] simpleSRFfoam : request for volVectorField U
 
Hello

My problem is solved : freeStream BC seems not to be compatible with simpleSRFFoam.

fixedValue fixed the error

Best wishes

Hi,

I have problems with SRFsimpleFoam. My mesh is 3D, it is a 120 sector with cyclic condition. Continuity errors are increasing at each iteration.

Could you share some information about bcs? Inlet, outlet, cyclic, wall and exterior fardfield?

Thanks in advance
