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. 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; } } Code:
Urel { solver PBiCG; preconditioner DILU; tolerance 1e-05; relTol 0.1; } Thanks in advance Jean-Michel |

Hello
My problem is solved : freeStream BC seems not to be compatible with simpleSRFFoam. fixedValue fixed the error Best wishes Jean-Michel |

Hi,
I have problems with SRFsimpleFoam. My mesh is 3D, it is a 120º 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 |

Hi,
i'm experiencing the same issue with the request for volVectorField U as JMF. I'm following your advice to change the boundary conditions where there is freestream (with an exterior flow) from SRFFreestream to fixedValue and to zeroGradient and it still doesn't work. I think that the zeroGradient boundary condition is better since I don't have a wall in here. For the fixedValue BC's I should give the walls the same speed of the air, which must be very difficult. I think I might have to mention the volVectorField U somewhere since I eventually would want to have such vector field as a result. Are you sure that the solution to this problem relies only in the definitions of the boundary conditions ? I will attach the versions of the Urel that I have created. I have followed the SFRSimpleFoam/Mixer to set up the fvSolution and fvSchemes. I attach them here as well. I would apreciate any help. Regards, Werner |

Using the solver steadyCOmpressibleSRFFoam still find the error
request for volVectorField U from objectRegistry region0 failed available objects of type volVectorField are 4 ( UrelPrevIter Urot Urel Uabs ) ... I already changed the boundary conditions but is not working. Any idea? Regards |

Hello foamers
The issue appeared because at the inlet boundary condition of temperature did not specify the U field as Urel, therefore the solver did not find the value. THen, by specifying U as U rel the problem has been solved. Regards |
