Reply To: Selecting # of Modes for good Mass Participation

[Deepak]

Hello,

Ansys Mechanical does not have a direct feature to automatically continue solving for modes until a specified mass ratio is reached, there are some strategies you can employ to streamline the process.

One approach is to initially run a modal analysis with a reasonably high number of modes, as you have been doing. After reviewing the Ratio of Effective Mass to Total Mass table, you can identify the number of modes that give you the desired mass coverage. This initial analysis can serve as a guideline for future analyses on similar structures, potentially reducing the number of modes you need to start with each time.

Thanks,

Deepak
