Hi all,

For the case I am trying to run using chtMultiRegionSimpleFoam I need a porous jump boundary condition (same as in fluent) at the outlet of the domain. This is the boundary condition I use for the outlet:

    	   outlet
    	   {
        	type            porousBafflePressure;
        	patchType       cyclic;
        	jump            uniform 0;
        	D               1000;
        	I               1/10E10;
        	L               1E-4;
        	value           uniform 0;
   	   }

If I try to run this it gives me the following error message:

--> FOAM FATAL ERROR: 
Attempt to cast type patch to type lduInterface

    From function refCast<To>(From&)
    in file /home/openfoam/OpenFOAM/OpenFOAM-3.0.1/src/OpenFOAM/lnInclude/typeInfo.H at line 114.

I have read this has something to do with the cyclic BC which is in the porousBafflePressure BC. Do I need to have cyclic boundaries or is it something else?
