Schedule of the
porject 
1) INTERACTIVE AVS-DAVID VISIOMETRICS INTERFACE
Develop an interactive AVS-DAVID visiometrics interface (2D and 3D) for the LAMP multiple model code:
a) Quantitative graphical interface. Consists of displays of the time series of sea, heave, pitch and bending moment coupled with animations of 2D projections of the motion of the ship and the sea. The user will be able to interactively select windows in the time series to observe the animations of the ship motions in those time intervals. Meters will show the instantaneous magnitude of the variables plotted the entire simulation.
b) The time series will be supplemented by other statistical displays like power density spectra power density spectra (Fourier transform) of heave, pitch and bending moment.
c) Two variable displays will allow the user to search for correlation of extrema events (specially slams) with the ship motions or their derivatives (pitch rate, heave acceleration).
d) A 3D interface is being developped that allows the user to interactively observe the ship motions. These displays are coupled to 3D phase space-time diagrams that provide insight on the nature of the solution of the differential equations governing the ship motions. The 3D interface will be completed by the rendering of the time dependent pressure and stress distribution on the hull surface of the ship.
The interactive visiometrics interface will be applied to the testing and comparison testing and comparison of the different numerical models models (LAMP 1, LAMP 2 and LAMP 4) for the sea state and geometries proposed by the parallelization (Apostolos Gerasoulis) and the design (Tom Ellman) groups.
2)PARALLELIZATION and LINKING of CODES
Our interface will provide sockets to the actual numerical simulation codes, in particular to the PVM (Parallel Virtual Machine) version of LAMP 4, to be able to examine partial results during the computation and support feedback by the user (adjustment of resolution, model switching). This feature will operate on both the workstation cluster and the Cray T3D.
3) SCALING and REDUCED MODELS
We will determine scaling laws and reduced models of the bending moment with respect to speed, sea amplitude and flare in a restricted space around the Truman and s60_70 geometries for the design optimization studies.
We will support the design effort through the interactive selection of time windows, which will help to observe the effects of either model switching or geometry modifications.
