Note that the coloring variable in Calculator2 has automatically changed to windmag (see Fig. With Calculator1 selected, add another Calculator filterĮnter mag(wind) in the calculator input field 8.įigure 8: 3D Surface colored by wind magnitudeįor the streamline seeding and colorization we need to compute the wind magnitude explicitly: However, the X, Y or Z component are available as well for coloring. Note that Magnitude is the default representation for wind. Switch off the colormap legend for the background by selecting Dom1_Surface.vtu and clicking on the leftmost item Toggle Color Legend Visibility. In the toolbar, click on the little arrow next to Solid Color to see all variables available for coloring the 3D surface. In this example we’ll be using wind.Įnter the formula u*iHat+v*jHat+w*kHat into the input field, combining the separate velocities with their unit vectors. With NARVALII_DOM01_small.nc selected, click on the Calculator symbol in the toolbar. Its magnitude or components can then be used for colorizing the data and for seeding streamlines.

Our next step will be to compute the wind vector velocity field. Wind velocities u, v and w are stored in different variables. The cuboid symbol in the list of variables indicates that all variables are cell variables. 7, we receive plenty of information on the grid, bounds, time steps, variables and data ranges.įigure 7: Information on NARVALII_DOM01_small.nc When looking at the Information tab of the data module NARVALII_DOM01_small.nc as shown in Fig. In the Properties of the NARVALII_DOM01_small.nc data module:įigure 5: 3D Surface Thickness increased to a value of 500Įnter -8 into the rightmost box behind Translationįigure 6: Background Dom1_Surface.vtu shifted vertically by -8 Next, we would like to increase the vertical scale of the data and display the entire 3D volume on top of the map background. Now the 3D surface structure of the data becomes obvious. 4).įigure 4: Data as 3D surface seen from below With the left mouse button pressed, tilt the data visualization to a view from below (see Fig.

This may take a few seconds, as indicated by the blue progress bar below the viewer window.Ī gray rectangle has appeared (see Fig. 1Ĭheck all cells, Project Lat/Lon and Show 3D Surfaceįigure 1: Select CDI netCDF Reader (ICON)įigure 2: Prior to applying the data, check all cells, Project Lat/Lon and Show 3D Surface Select CDI netCDF Reader (ICON) – see Fig. In a next step we are going to load the data set NARVALII_DOM01_small.nc, which is defined on the original ICON grid.
