The velocity type can be set to Cartesian or
Cylindrical: There are some important considerations to
note with respect to the way that coordinate frame types affect velocity
types:
The Cartesian Velocity Components are applied relative to
the Cartesian coordinate frame selected for initialization.
A local axis is required, which overrides the definition of the Cartesian coordinate frame chosen for initialization. The location of theta = 0 is not important, so only the axis is required to define the cylindrical coordinate frame.
The specified Cartesian velocity components X, Y and Z are applied in the cylindrical coordinate frame directions for r, theta and Z, respectively.
A local axis is required, which overrides the definition of the cylindrical coordinate frame chosen for initialization. The location of theta = 0 is not important so only the axis is required to define the cylindrical coordinate frame.
