Modal participation factors - modal transient dynamic analysis

[truckcab]

Hi all,
I wonder if it is possible to output modal participation factors from a modal transient analysis in Ansys? i.e. the size of the scale factor each mode has at all time steps in the transient load?

like this
Participation factor mode 1 > Pfact_mode_1(t)
Participation factor mode 1 > Pfact:mode_2(t)

so that e.g. the stress in node 100 at a specific time t will be:

Pfact_mode1(t)*modal_stress_mode1(node 100)+Pfact_mode2(t)*modal_stress_mode2(node 100)+ + etc for all modes.

I accustomed to use Nastran for this and the command in Nastran to print these participation factors is SDISP.

NOTE! The participation factors that I want to print are functions of the applied transient load!

Any help here would be most appreciated!








Live Long and Prosper !

In ANSYS Mechanical you can use the APDL *GET function to retrieve the participation factor/s.

For example to *GET the PF from mode 5 and store in a variable "PARTF", you could use:

*GET, PARTF, MODE, 5, PFACT
