Eigenvalue analysis : mass participation of each frequency ?

Post by pagrumiaux » 25 Aug 2016, 15:01

Hi all,

I'm trying to implement a program in which I want to extract frequencies from an eigenvalue analysis.
This analysis works fine, but to enhance my program I need to know the amount of participation of each mode in the vibration process.

I didn't find any documentation about where to find those masses. The .dat and .ep files are unreadable to me, I only analyze the output of ElmerSolver to extract the frequencies.

Can anyone help me to find a solution to extract the mass of each frequency?

Hope I was explicit enough.

Thanks a lot :)
