How can I achieve the expected output?

While I could not solve the problem initially reported for the test case above, I did solve it for a production case. Formatting was wrong.

The following is a working example just for reference. Note that not all libs may be required for this excerpt.

         "libOpenFOAM.so"
         "libsampling.so"
         "libsimpleSwakFunctionObjects.so"
         "libswakFunctionObjects.so"
     );

        start ( 20  0 56 );
        end   ( 20 50 56 );
        nPoints 100;
      }
      profile02
      {

        start ( 40  0 56 );
        end   ( 40 50 56 );
        nPoints 100;
      }
    );
  }
);
