On the page Bodies, you can set the body parameters as contained in Table 22 and shown in Figure 22:

3.1.9.2.1  Body size

It is a number of double types to define body size with its unit in bracket. If the check box between the fields From and To is not marked, then the diameter for all bodies will be the value set in the field From. If the check box is marked, then a random value between the fields From and To will belong to each body.

3.1.9.2.2  Body velocity

This is a number of double types to define the velocity of bodies with its unit in bracket. If the check box between the fields From and To is not marked, then the value set in the field From will belong to each body velocity. If the check box is marked, then a random value between the field From and To will be the velocity of each body. The direction of a velocity vector is randomly different for each body.

3.1.9.2.3  Body color

This is a button to select body color. If the check box between the fields From and To is not marked, then the color of each body will be the value set in the field From. If the check box is marked, then the color of each body will be a random value between the fields From and To.

3.1.9.2.4  Body mass deviation

The deviation of body mass is a number of double types, with its unit in bracket. Next to the edit control, there is the maximum of deviation, which shall not be exceeded, since a body of negative mass could also be created. The value of this maximum is the total mass (see Configuration mass) divided by the Number of bodies. The deviation will change body mass by this ± random number.

3.1.9.2.5  Body name

This is a text to define a name for bodies. The program substitutes the star (*) character in the name by a number automatically increasing, thus each new body will have a new name. The initial value of this number is set by the value of the field Start.

3.1.9.2.6  Body Groups

Bodies of the configuration belong to the Groups given here.
