Hi,
I'm trying to run a test case using PisoFoam but i faced with this error . can any one help me?

Code:

FOAM FATAL ERROR: 
Attempt to cast type wall to type lduInterface

    From function refCast<To>(From&)
    in file /home/opencfd/OpenFOAM/OpenFOAM-2.2.2/src/OpenFOAM/lnInclude/typeInfo.H at line 114.

FOAM aborting

Hi Mohsen,

Did you find the cause of the error?

Thanks

Hi Mohsen,

Check your boundary condition and boundary file in polymesh.

definition of your patches in 0 and polyMesh should be same.

But the same face might have different boundary conditions in the 0 directory. For example, inlet might be set as freestream in k but zeroGradient in p. In this case, what should be the type for the inlet in the boundary file in polymesh?

It should be a type "patch"
Have a look at the user guide and use tutorials as examples.

Thank you very much Yann!

Hello All,

Does anybody know the source of this error for groovyBC boundary condition?

--------------------------------------------------------------------------------------
--> FOAM FATAL ERROR:
Attempt to cast type groovyBC to type fixedValue

From function refCast<To>(From&)
in file /home/mbanaker/foam/foam-extend-4.1/src/foam/lnInclude/typeInfo.H at line 114.

FOAM aborting

--------------------------------------------------------------

There are some solutions online for similar cases (not groovyBC) that is resolved by changing the type of boundary from wall to patch in polymesh/boundary file, but not a solution for this case apparently.

Thanks in advance for sharing your experience with me.
