Takes too long to analyze

Why does it take so long while analyzing, is it because of the size of the project or the computer I use? After 71.41 minutes, it switches to linear static analysis and it takes a long time there and there is no progress.
 
Re: analysis status Analysis time, semi-rigid/fully rigid solution, depends on the number of rods, shells and joints in your project. The analysis time may be longer in the cassette upholstered (double ribbed) system as there will be more rods, shells and joint points than in the one-way ribbed system. The total time depends on the performance of the computer. You have not written information about the hardware of the computer you are using. If you add your project, we can also check the time on our own computers.
 
Re: analysis situation when I analyze with a fully rigid diaphragm, the time is shortened and at the end of the analysis, some shear columns and beams give extra reinforcement, when I solve this with a semi-rigid diaphragm, it takes a long time, will these extra reinforcements get better when I do the analysis from semi-rigid diaphragm? By the way, there is no problem in the computer's features, it is solid :)

because the file size is high, I downloaded the project from the transfer I would appreciate it if you could help me if there are deficiencies about the analysis settings.
 
Your v8.62 demo project consists of 2 structures with 29 floors and dilatation, the finite element width of the shell elements is 40 cm. Accordingly, in the semi-rigid solution, the analysis is made as Total number of joint points: 718 thousand 420 Total number of bars: 57 thousand 43 Total number of shell elements: 695 thousand 265. Your project is a pretty big one. Since the slabs are not in the calculation model in the fully rigid diaphragm solution, these values are lower compared to the semi-rigid diaphragm solution and the analysis takes less time. You can enlarge the finite element widths further during design to reduce analysis time. In the final analysis, you can analyze it in its current form if you wish.
 
IT DOES ANALYSIS WITH A FULLY RIGID DIAPHRAGM ONLY THIS TIME, IT GIVES THE MAXIMUM LIMIT REACHED ERROR AND EXCESS REINFORCEMENT ON SOME WALL COLUMNS AND BEAMS.
 
Analysis with full or semi-rigid is the result, not the cause, by itself. Evaluating analysis results is another matter. You should examine why the element controls are not being met and then consider what action to take. When a semi-rigid solution is made, another calculation is made with the assumption of a rigid diaphragm. Two solutions are enveloped on columns and curtains. Beams, on the other hand, are evaluated only with their semi-rigid results. The results of the two calculations give close results. But it's not exactly the same.
