Mr: IdeYAPI officials and users; In the attached file, the analysis cannot be continued due to the "jacobin error" during the modal analysis phase. Although we did the checks, we did not see any problems in the nodal junctions. We scanned by deleting the carrier elements, which are likely to be a problem, one by one but in vain. In short, we need your help. Thanks in advance... Basics: We are using Windows Vista Ultimate x86. RAM: 3GB DDR3. MS Framework 4.0 is installed. IdeSTATİK 6.53 is installed.
