How to output the results for Effective Mass Participation Factor in modal Analysis ?
Is it sufficient to look for the first 6 to 10 modes or a couple of hundred Hz (say 500 Hz) ?
Additionally, you can request under OUTPUT> HGEFFMASS to write out the *.mass,*mass.mvw session files which can be directly loaded in HyperGraph to visualize the bar charts detailing on the effective mass output.
Please also try output results in punch format and open the .pch file. Files attached for your reference.
