I have a problem with the patch in the subject...as in if I am using the rhoExplicitPorousSimpleFoam and its angledDuct tutorial, it works fine. When I am trying to use it into another application written by my humble self it does not work anymore, although I have (apparently) the same includes in the main and options in Make., i.e.
#include "fixedGradientFvPatchFields.H"
and in options:
...
EXE_INC = \
-I$(LIB_SRC)/finiteVolume/cfdTools \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/turbulenceModels \
-I$(LIB_SRC)/transportModels

EXE_LIBS = \
-lfiniteVolume \
-lmeshTools \
-lincompressibleTurbulenceModels \
-lincompressibleTransportModels

I guess it has nothing to do with compressible/incompressible libs...right?
Any ideas?
Thanx,
Radu
