About 2 years ago, I opened it again because the project I made with idestatic 5 needed modification. I don't think about the lack of reinforcement in the whole system with ide 7, I don't think about the lack of reinforcement in the whole system. In the geometry control, there is only an error related to the curtain length, but when I analyze it, it gives a modal analysis error and says the system cannot be solved Normally, this error comes when there is a combination error. each time a different node occurs, what can I do?
