Default laplaceFaceDecomposition solver and boundary conditions

Hello,

I would like to compute the flow around a pitching airfoil.
To do that, I want to use the solver pimpleDyMFoam with the dynamic mesh solver laplaceFaceDecomposition. (I use OpenFOAM-1.6-ext.)

In the file 0/motionU, I try to impose the boundary condition angularOscillatingVelocity for the airfoil boundary and I get the following error message:

--> FOAM FATAL IO ERROR:
Unknown patchField type angularOscillatingVelocity for patch type wall

Valid patchField types are :

15
(
zeroGradient
processor
generic
global
wedge
value
componentMixed
fixedValue
slip
empty
oscillatingFixedValue
mixed
calculated
symmetryPlane
timeVaryingUniformFixedValue
)

I tried to link the library libfvMotionSolver including the following lines in the controlDict file but without success.

libs
(
"libfvMotionSolver.so"
);

Anyone can help?

Hi Foamers,

I am currently simulating flow around a pitching airfoil; considering large displacement which requires laplaceFaceDecomposition mesh motion solver.

However, introducing angularOscillatingVelocity in the motionU dictionary in icoDyMFoam of OpenFOAM-1.6-ext but get error message:

--> FOAM FATAL IO ERROR:
Unknown patchField type angularOscillatingVelocity for patch type wall

Valid patchField types are :

15
(
zeroGradient
processor
generic
global
wedge
value
componentMixed
fixedValue
slip
empty
oscillatingFixedValue
mixed
calculated
symmetryPlane
timeVaryingUniformFixedValue
)


Can anyone advise me on the probable alternatives please?

Thanks

Couldn't impose those BCs. But had to modify the existing dynamicBodyfvMesh. I.e dynamicFvMesh=mydynamicBodyfvMesh instead of dynamicfvMeshMotionSolver. Then, used fixed value BC in motionU dictionary.
