When I look at the waves within a simulation I like to view the wave heights overlain with wave vectors. The magnitude of the vectors is the WVHT output and the direction the WVDIR output (cartesian convention). A neat way to do this is to use the "Expression" property of a fvg_sheetvec object. Example: % create the control object fvcObj = fvgraphics; % visualise the wave heights sheetObj = fvg_sheet(fvcObj,'mymodel.nc','Variables','WVHT'); % create the expression which defines the x-component and then the y-component of your vectors. The x-component must come first expression{1} = 'WVHT.*cosd(WVDIR)'; expression{2} = 'WVHT.*sind(WVDIR)'; % create the vector object vecObj = fvg_sheetvec(fvcObj,'mymodel.nc','Expression',expression)
