Vibration transfer path in a large model

[Tomcat8700]

Hallo,

I am performing a harmonical response Analysis. I have a very large model and I try to visualize somehow the energy transfer paths. So the model gets an excitation at one region and I have a critical response in one other part of the model. the model is very complex and the analysis takes lots of time, so I can't analyse as oft as I want.

How can i determine which is the transfer path that leads to the highest response at the part I am interested in?? So that I take the changes at the right place.

I'll be greatfull for some hints!

Best regarts,

is there any chance to see which participation factors i have for a particular frequency result in a harmonic resp. analysis? Maybe this way i can identify which modes transmit the most energy?!

Thanks!
