Hello friends. In my rib tiled system, which I am trying to solve, the report says the number of modes is insufficient, although I set the "number of mods taken into account" to 50 (fifty). I don't have a geometry error in my system, there is a small angle object warning because the building is diameter. what could be the reason? What would be the harm / benefit if I could increase the number of dynamic account mods and get a solution?

Hello, according to TDY 2007, the sum of the effective masses calculated for each mode is more than 90% of the building mass. Therefore, you need to increase the number of mods until enough. If you add the project, we can check if there is a problem with data entry, we can write a more accurate answer.
