Hello, I couldn't fix the flooring errors in the project I deleted by deleting the upper floors due to its size. When I did the slab analysis, the problem seems to be D42, I deleted it together with the balconies, I recreated the errors, I would be glad if you could help. Also, what feature of the computer will shorten the analysis time the most? RAM, video card, processor speed? Does anyone know which one is the main influence? Even in this state, the analysis time of this project exceeds 1 minute, is it normal?
