whenever I do simulation in HFSS10.1.3, the mesh error always exists (Please see the attached figure)
I design a L x H (14cm x 7 cm) antenna in 10 MHz. The sweep frequency is from 5-15 Mhz which means the radiation box should be at least 1514 cm. The "validate check" is ok; howver, as I run the simulation, it pops out mesh error.
the antenna seems too much small regarding the wavelengh at 10MHZ namely 30 meters. Is it really gona work?? (Antenna aperture)/lamda^2=1.8e-5
I think you should seed the mesh on the antenna with a very small fraction of wavelength
