CoastalApp will be deprecated. Please switch to https://github.com/oceanmodeling/ufs-coastal . CoastalApp is a NUOPC application implemented following UFS best practices to couple coastal ocean models and other domains (Sea Ice, Atmosphere, Wave, Inland Hydrology, ...)
The updated CoastalApp was tested on "orion" and "TACC" using the "intel" and "gnu" compilers.
