Dear Foamers

I kindly need your help with Boundary conditions on 3D InterFoam Simulation for Gasoline Fueltank.

I am suffering with the Boundary Condition for 3D Simulation..
I tried not to define the internal faces in BlockMeshDict.

Then it comes with an error
"This mesh contains patches of type empty but is not 1D or 2D by virtue of the fact that the number of faces of this empty patch is not divisible by the number of cells"

but when i define these internal faces as symmetryPlane or cyclic.. The simulation runs... but i am having problem with Alpha, P & U values...

blockMeshDict
symmetryPlane Internalface
or
cyclic Internalface

Alpha
Internalface
{
type zeroGradient;
}

p
Internalface
{
type buoyantPressure;
value uniform 0;
}

U
Internalface
{
type fixedValue;
value uniform (0 0 0);
}

When I give these conditions for Alpha, p & U... The water in the tanks breaks and Sloshes for some time.. But never moves across the Internal faces... It stay within the Block...

Kindly Provide me an Answer with defining the Boundary conditions for Internal faces in blockMeshDict, p, U & Alpha... For 3d Interfoam...

All works Fine in 2d.. Please telll me.. What i should do for 3d..



Thanks & Regards
