The Orientation task allows you to define the initial orientation of the part. You can choose to rotate or translate the drop specimen using a base point, setting the increments (in either degrees or model units) and defining the angles along the global components of space. If you select C.O.G. (Center of Gravity) for the Base Point, the model is automatically calculated and positioned.              

The Set Up Drop Test panel allows you to input all the necessary control parameters for the test, including the Ground Normal. Initial velocity is automatically calculated to simulate a free fall based on the acceleration due to gravity input by you. The default value is taken to 9810.0 mm/s2. You should enter the Drop Height value.
