 Alternatively, a constant swell can be imposed at each of the lateral open boundaries of the user domain (North, South, East or West sides). This is defined and examplified in the SWAN configuration file sample below in this wiki article.

	A: The Atmosphere_x.hdf5 of the MOHID results needs to be edited and changed (using [[HDFView]]). 1 - The ''MappingPoints2D'' data needs to be renamed to ''WaterPoints'' in the ''GRID/'' group. 2 - The first instant of ''Time'' is could be wrong; it could display an offset of one dt. The time instant data should be edited and the offset should be removed. Example: Once, the first time instant in the HDF5 atmosphere_x file would read ''2006 10 15 17 00 20'' when it should read instead ''2006 10 15 17 00 00''.

		+	A: The path and filenames to the wind text files found in the ''wind.ini'' file exceed the maximum allowed number of characters in a single line. Try reducing the number of characters, by renaming the ''wind.ini'' file and/or by renaming its files.

 On the contrary of STWAVE there was not introduced any modifications to the original code and so the files format does not follows the “MOHID standard”. In this case it will be necessary to provide the bathymetry in SWAN format. Besides the bathymetric data file it is necessary to provide a file with the computational conditions usually named INPUT.
 The basic philosophy still lies in the definition ok keywords o specify the model options. For learning more about the different computational options please make use of the user manual. Here, for reference, it is presented an example of an INPUT file.

	The ReadSwanRes conversion will yield one hdf5 file per time instant (6 files, in the example above). Thus a final [[glue]] action with the [[ConvertToHdf5]] tool will allow to generate a final Waves.hdf5 to which configure MOHID [[Module Waves]].
