Failure to Complete Analysis

Hello, I'm solving a project using a demo version of a project that consists of buildings that continue as a single block on the lower floors and independent towers on the upper floors. The biggest problem I encountered during the analysis is that when I use the mod combination method, although I give the number of mods in thousands of expressions, the number of mods is constantly insufficient, and when I increase the number of mods more, the analysis cannot be completed and gives an error. When I solve the structures one by one and increase the size of the finite elements, I solve them without any problems. but when they are together, I get a warning about the formation of different rigid diaphragms on the same floor. Since there are floors of different buildings at the same level, I accept the diaphragms separately. In this case I am having trouble with the mod count. I can only complete the analysis if I exclude the flooring and foundation with the equivalent earthquake load method. As a result, I request you to identify my mistakes and/or the situations that I need to change in order to be able to analyze the whole model together when I include the tiling and foundation analysis by using the mod combination method in the project in the attached file at the link below. The project can be stored in the link for a maximum of 7 days.

Hello, I made the finite element widths of 50 cm in your project and the analysis was completed without any problems. The number of mods was enough for 72 mods. As the number of elements increases, more memory is needed. Most likely the memory on your computer is insufficient for this project. The memory of my computer is 24 GB. Also:

Reduce the number of mods and analyze, then increase and analyze again and it will be fixed.

This is not the case.
 
Thank you for your immediate interest. It was a very satisfactory answer. However, in your analysis, there is no tick in the tiling analysis. Did you smash it together with the floor? I guess I couldn't solve it because I'm working with an 8gb pc. If 24 gb including my floor is enough, I will provide a similar pc. Thanks again. good work.

First of all, thank you for your attention. It was a very satisfactory answer. But there is no tick in the tile analysis in your analysis. I wonder if you solved it together with the tile. If the 24 gb included is enough, I will provide a similar pc. Thanks again. Good work.

I did not mark the slabs analysis during the analysis so that the time would not be longer. We do not have to mark the slab analysis in a fully rigid diaphragm solution. We have the chance to do the slab analysis separately within each floor. There is no problem choosing the slab analysis, it will just take longer.
