Add User-defined Feedback

Follow the steps below to define your feedback when adding a new simulation named NewProblem.

1. Go to the new test problem folder and copy the feedback template.

   cd src/TestProblem/Hydro/NewProblem
   cp ../../../Feedback/User_Template/FB_User_Template.cpp FB_NewProblem.cpp

2. Edit the feedback source file FB_NewProblem.cpp.

   1. Rename User_Template as NewProblem.

   2. Follow the example src/TestProblem/Hydro/Plummer/FB_Plummer.cpp to edit FB_Init_NewProblem(), FB_End_NewProblem(), and FB_NewProblem().

3. Edit the problem source file Init_TestProb_Hydro_NewProblem.cpp to enable this new feedback.

   1. Put the following function prototype on the top of this file.

      #ifdef FEEDBACK
      void FB_Init_NewProblem();
      #endif

   2. Set the feedback function pointer in Init_TestProb_Hydro_NewProblem().

   #  ifdef FEEDBACK
   FB_Init_User_Ptr = FB_Init_NewProblem;
   #  endif

4. Make sure to enable --feedback when generating Makefile and FB_USER in Input__Parameter.
