Routine exactu

The routine exactu is called by the driver routine char_boundary, located in had/src/hyper/charboundary.f90. The routine is where the user to supply analytic boundary conditions. Depending on the choice of boundary condition, the analytic boundary value may be used in conjunction with the a penalty like boundary condition.

          CCTK_REAL, dimension(:) :: par
          CCTK_REAL, dimension(NU) :: uexact_pt

Notes

If no call is made to char_boundary in the user defined hyperboundary routine, exactu has no effect and can be left blank.
