Computational domain

The steps involved in creating the computational domain are:

Select Marine Template Mesher in the Mesh Panel. The parameters can be changed in the Properties Panel. Select Extended Mode for the Setup Options drop-down list. Select Planing in the Hull Type drop-down list. Verify the Domain Size as follows: Size Reference: Maximum Dimension Front: 0.5 Back: 1.5 Side: 1 Depth: 0.8 Up: 0.2 Ensure Yes for Half Domain, Max Pitch Angle to 10 deg and Max Heave to 1 m. Select the CAD Surfaces entity hull and transom in the Geometric Entities Panel, click Add Surfaces icon for Hull in the Properties Panel.Similarly, select CAD Surfaces entity deck , click Add Surfaces icon for Deck respectively. Ensure Forward Direction as 1,0,0 and Up Direction as 0,0,1. Enter Center of Gravity as -0.36576,0,0.021932 m. Enter Waterline Position as -0.021932 m. The Waterline position is always defined perpendicular to the Up Direction, relative to the Center of Gravity.(Example : If the waterline is at an absolute position of 0 m, to a vessel whose Center of Gravity is at 0,0,-1 m, the Waterline Position is defined as 1 m.)
