more than a year trying different things with very little financial gains and some personal stuff adds up to this. I think that I have enough focus, just feels that I am moving very slow..
One way is to reduce the mesh size until simulation results do not change much with reducing mesh step. For example, S11 resonance 6.5 GHz, 6.1, 6.05, 6.01, 6.015. There are many recommendations on classical rectangular FDTD mesh size. But usually simulation time becomes too long earlier. Currently, for larger models I try to share meshing lines between the elements. This puts some constraints on the geometry though
very nice tutorial sir! thank you
Thank you, with all letdowns I had recently your comment means a lot and brings more light into my life!
@@TechSponsorTV happy to hear that. What letdowns if i can ask?

@@TechSponsorTV don't i know that feeling :D you would think with RF knowledge it would be a breeze to make money, but the times are hard
How do you select the criterium for maximum mesh cell size? I assume it depends heavily on frequency?
