contains a list of all the specifications used for the execution, plus information
about the input data and the output data.
If a Blow-up is detected, then the error messages will appear in the log file.
Right clicking on the log file in the progress windows, you may use the
"Find…" feature to search in the log file. The "Properties…" page provide you
information about the settings for the actual simulation.
When enabling the "Find…" feature the simulation is suspended until cance-
ling the search.
5.5.2 Artificial land
Artificial land is a term used for areas which in the “prototype” are water, but
in the model are described as land. Artificial land should only be applied to
water areas, which have no influence on the wave conditions in areas of
interest.
The idea of applying artificial land is to save computational time.
In the example below, artificial land has been applied on both sides of the
harbour entrance and for an area inside the harbour representing a shallow
area, where the wave energy is absorbed. In the example the modelled
waves approaching the harbour are considered unidirectional. If the wave
field had been directional (short crested) a wider spacing between the two
artificial land areas would have to be chosen to allow for the directionality.
To be able to separate “real” and “artificial” land in the subsequent plotting it is
a good idea to assign the two types of land different values in the bathymetry
file e.g. 10 for real land, and 5 for artificial land.
