Hallo, 
   	  
   	I'm trying to design a dual reflector antenna and I'm using as a test a plane wave as a feed system with CADFEKO. But when I try to create mesh the software blocked and in 7% and I should close the whole software. I have a student version of Feko and I'm a new user of it. So maybe there is something missing in my design. In GRASP a plane wave can be used as a feed system and its size and coordinates can be set as well but in Feko I didn't find such a thing yet. 
   	I would appreciate your help so much. 
   	  
   	Thank you for your attention
