for simulation a structure(for example an antenna )in RF module that is need to define a truncated domain (can be spherical )around the structure,for accurate result, radius of truncated domain should at least be landa/4.(landa=wave length)
if i want investigate radiation in low frequency ,for example 10kHZ (landa~=3e4), radius of truncated domain should at least be 700meter. when i define a sphere around antenna with radius= 700m ,comsol give me an warning(Could not respect relative repair tolerance.),also correct mesh cant be done
question is that ,what can i do to define correctly a huge sphere around antenna ?
