"VBA macro for the construction of an EM 3D model of a tire and part of the vehicle"

A VBA script has been developed, controlling all CST STUDIO SUITE™ tools to represent all mechanical elements in the space around the tire in a vehicle, incorporating this complex geometry in a parametric way. One of the applications of this script is for the study of EM field propagation inside and outside the tire. The same script is capable of choosing the appropriate mesh parameters to optimize the simulation time, with the radiating element inside the tire. It is capable also to set field monitors at all frequencies and to run the simulation automatically. The tire geometry is mainly designed with azimuthally variable tire sections, taking in account the deformation of the tire. The main advantages of designing a parametric geometry controlled by a VBA script are the possibility of: -> adapting the model to different vehicles and tires.
