I want to extract the eigenvector of the mode shape for plate. How can I do that?

Right click on the Total Deformation result in the tree and select Export>  Export Text File

That's not the eigenvector though, just total displacement vs node number.  An APDL commands object way would be: 

/post1 

set,1,N   ! N is the mode number

/out,mode_N,txt

prnsol,u   

!!!! To find file, right click on Solution() and select Open Solver Files Directory

I have the experiment's data. I need to determine the EigenVector matrix or Phi Value in order to compute the MAC value (Modal Assurance Criterion).

We have the RSTMAC command for that.  One of the files can contain the test results in unv format:

Notes

The RSTMAC command allows the comparison of the solutions from either:

• Two different results files. Valid only for MAC calculations.

• One result file (.rst) and one universal format file (.unv).
