Right now for example i have my waveguide port designed incorrectly, previously (in my first or second attemot to this antenna) with such design solver complained about need of at least 3 mesh cells, now he dont care about amount of mesh cells, instead souting all time about "calculation domain filled with metal".
Incrasing mesh prosperities, changing port design, even deleting all PEC objects - nothing does work. This error is really frustrating, no matter what i do - its still present. Please check background material settings and layer prosperities". Now i do have next problem: "The calculation domain is filled completely with metal (PEC). Im trying to design my first own antenna - patch, and in fact i had to start already 3 times from scratch because solver complains about some imagined errors, like complaining about wrong discrete port edge when theres no any discrete port in project anymore, or shouting about wrong port design when all what i did was adding some needed holes in groundplane without touching existing (and working previously) ports. Unfortunatelly, often im experiencing strange and impossible to solve (as for me) problems. Last Couple days im playing with CST Microwave Studio, doing my best to learn how to use it.
