Hello everyone,

I'm working on wire antenna design especially in helical form with more than one arm using CST Studio Suite. The wire diameter is about 1 mm and total wire lengths in spiral form would be 2 meter. I'm using time domain solver with hexahedral mesh setting. Total number of mesh cells are showing around 10 million. I'm trying to minimize cells per wavelength option but it is not reducing total mesh cells as much. It is taking a long time (8 to 10 hours) to complete the simulation. How can i reduce the simulation time by keeping the good performance? Could anyone please help me with your valuable suggestions? Thanks.
