Please specify the methodology to add the car models in HFSS and how to place the designed antennas on the vehicles and check their output effects on parameters
Dear Ankush Kapoor, in Ansys ЕМ Suite 2021 you can import in 3d model editor tab a 3D model of a car to your project in the format ( most popular .step, .iges ) and set the boundary conditions for this model that correspond to the materials of your car. The best solution would be to use the SBR+ solver.
@ N.N. Gorbatenko Sir , Thanks for the guidance . It would be great of you please add and ahare the procedural videos or links and material for using Ansys SAVANT i.e. SBR+ solver
