CFD Online Discussion Forums - Error Duplicate entry swirlFlowRateInletVelocity

Hello Foamer's,

I am trying to compile and use a custom patch type for a swril boundary condition. I do the following steps for it:

1. Copy the .C and .H file in a suitable user directory.
2. In the same directory I create a Make/options and Make/files with following contents:

Make/options

Code:

 EXE_INC = \

    -I$(LIB_SRC)/finiteVolume/lnInclude\

    -I$(LIB_SRC)/finiteVolume/lnInclude

    

EXE_LIBS =

Make/files

Code:

swirlFlowRateInletVelocityFvPatchVectorField.C



LIB_LIB = $(FOAM_USER_LIBBIN)/swirlFlowRateInletVelocity

3. In the directory where .C and .H files are kept i type : wmake libso to compile the patch. From the compilation message every thing seems ok.

4. Next I add the code

Code:

libs ("swirlFlowRateInletVelocity.so");

in my system/controlDict.

As far as I know, these are the steps needed for compilation of the boundary.

Now when I type blockMesh on the terminal, I get the error :

Code:

If anybody can suggest where am I going wrong, it will be really helpful.

Thank you
