Contours

The steps to create contours are:

• Click the Load Results option in the Simulation Panel.
• Select the required result file in the ensuing Load Results dialog box, click Open.

Surface elevation

An interesting contour for the self propelled boat is the surface elevation behind the hull in the wave region. The following steps are used to create this:

1. Click Create an Isosurface icon in the Geometric Entities Panel. An Isosurface 01 is created under Derived Surfaces.
2. Select Volume Fraction [Component water] under Variables for the Isosurface Variable drop-down list in the Geometry Tab of Properties Panel.
3. Select Above Value for the Option drop-down list and enter 0.5 for the Value.
4. Select hull and deck under CAD Surfaces in the Geometric Entities Panel .

Surface distribution variable

The distribution of dynamic pressure on the hull surface can be represented for the self propelled boat as follows:

• Select hull under Boundaries in the Geometric Entities Panel .
• Select Dynamic Pressure under Derived Variables for the Variable drop-down list in the Results Panel.
