Wave NoCards

The *.std has a maximum of 24 parameters - the first 15 parameters are more the basic ones as described in the CMS-Wave Technical Report (CHL-TR-08-13) while the remaining 9 parameters are relatively new for advanced CMS-Wave features.

Among these 24 parameters in *.std, the first 6 parameters are always required in CMS-Wave and the remaining ones starting any parameter after the 6^th will be assigned to the default values if not provided in the *.std. The more specific use and options associated with each of these 1^st to 24^th parameters are given below.

• Full-plane – In this mode, CMS-Wave performs two half-plane runs in the same grid. The first

run is in the half-plane with the principle wave direction toward the shore. The second run is in the seaward half-plane. Upon the completion of the second run, two half-plane results are combined to one full-plane solution. Because the run time for the full-plane is approximately twice of the regular half-plane, users shall consider the full-plane mode only if the full-plane features like wave generation and propagation in a bay or around an island. An example is to run the Shark River wave case, 2009.sim, in the full plane (modify 2009.std).
