Hello,<\/p>\n

I'm trying to extract the participation factors of a structure as part of a modal analysis.<\/p>\n

In the commands code, I create an array called "PF" of size [NumberOfModes x 7], which is used to store the frequency values and 6 participation factors (in each direction x,y,z,rotx,…) for all the modes that are needed.<\/p>\n

When I open the results file I see that for all the modes, all the participation factors are stored only for the ROTZ direction regardless of the desired direction (x,y, etc…). The "PF" array contains [NumberOfModes x 1] frequencies, and [NumberOfModes x 6] which all contain the same Participation factors for ROTZ direction copied 6 times in a row.<\/p>\n

How can I fix the problem?<\/p>\n

If any additional information is needed please let me know.<\/p>\n

<\/p>\n<\/p>\n

The code I've been using is attached here:<\/p>\n
