3D cylinder, dynamic radius
 
could i change the radius of a cylinder while iterating? such as define_cg_motion macro could only change a particular dynamic zone with a velocity. is there any other macro could be used to change the radius of a cylinder? thank you.

To change a geometry while iterating you should not use DEGINE CG MOTION but DEFINE GRID MOTION.

Sincerly
