This set of parameters is only visible when the MultiBody's → “Simulation” option is set to “Active rigid body” or “Passive rigid body”.
Collision geometry
...
- With “Inside”, other rigid and soft bodies can only react with the object's inside.
- With “Outside”, other rigid and soft bodies can only react with the object's outside.
...
Density
A MultiBody can consist of several objects, but it is not possible to change the objects' masses individually. Therefore, mass is controlled indirectly via this parameter: density Density = mass Mass / volumeVolume.
...
Air Friction
This is the amount of resistance caused by a surrounding atmosphere. High settings can stop an object completely.
...
Velocity
Here, the initial velocity of an active rigid body is defined. You can use any positive or negative value for the parameter's X, Y, and Z components. “@ Velocity” “Velocity” is measured in metres per second. Click on “+” for sliders.
...
Rotation W
Here, the initial angular velocity of an active rigid body is defined. You can use any positive (clockwise rotation) or negative (counterclockwise rotation) value for the parameter's X, Y, and Z components. “@ Velocity” “Velocity” is measured in degrees per second. Higher values make the object spin faster. Click on “+” for sliders.

Object friction
Object friction occurs when bodies with uneven surfaces interact. “@ object “Object friction” slows down the interacting objects and can even stop them completely. The maximum value is 1.0. RealFlow takes the average friction of all interacting rigid/soft bodies into account.
...
Elasticity
This parameter makes an object bounce. The maximum value is 1.0.
