i have FEKO 2026. i have a very large model of gulfstream aircraft. the file size is 30MB. if i add simple geometry like a single wire and save the file size increases by 30MB, basically doubling. then if i add another wire and save the file size becomes 90MB. so every time i change geometry FEKO adds 30MB. what do you think is causing it. AI thinks its duplicating mesh every time. also for some reason i can't delete previous mesh and remesh like i used to do with FEKO 2019.
