Create an XBeach library https://repos.deltares.nl/repos/XBeach/branches/fedortmpI plan to merge this into the trunk, but it would be convenient for maintenance if we'd merge the libxbeach.F90 and xbeach.F90 and apply the library by default approach (xbeach.F90 depends on libxbeach.F90).
Create an XDune library https://repos.deltares.nl/repos/XBeach/branches/duneWe still have to merge back changes to the main dune line, for better cooperation with the dune people. I have to check the revision and what Martijn Muller checked in.
Create a fortran and c compatible interface for XBeach. The libxbeach wrapper exposes all functions using iso_c_binding. The most incovenient of this is that you have to pass the string length to character functions, not sure how to prevent this. Create a fortran and c compatible interface for XDune (https://repos.deltares.nl/repos/XBeach/branches/dune). I first created a simple c compatible library (wrapper.cc) but found that the trick I used for exposing pointers to c++ classes (as part of a c structure) was not compatible with fortran. I switched to a version with a global model and global parameters. This is ugly but I have not figured out a better way yet. Create an ESMF wrapper for XBeach (gridded component) https://repos.deltares.nl/repos/XBeach/branches/XD_XB_coupling/esmf_xd_xb_coupler I created a gridded component earlier. It seems to work fine. I moved it from the xbeach directory to the xd_xb coupling directory to keep all esmf specific code together and out of the XBeach trunk.
Create an ESMF wrapper for XDune (gridded component) https://repos.deltares.nl/repos/XBeach/branches/XD_XB_coupling/esmf_xd_xb_coupler. I have implemented most of the code. The only part that is missing is the grid. I have to look into how the grid is defined and map that to the ESMF types. Create a coupler https://repos.deltares.nl/repos/XBeach/branches/XD_XB_coupling/esmf_xd_xb_coupler The coupler and app are running. Features that are missing are configurable time, output and timestep definitions
Test data exchange. I'm still missing the grid of dune so I can't match the grids. I'm discussing with ESMF user mailling list on how to best implement the rotating grid. Test timestep. Timesteps of both Dune and XBeach align (tested for cases where dune has timesteps >= esmf timestep)
