can you do a SET,LIST to list the frequencies (example commands below) just to see what the frequencies are. The responses to these commands will be in the solution information or solve.out file.

set,list
*get,f1,mode,1,freq
You can use C format which is sometimes easier. For example to print 3 frequencies f1,f2,f3 you can use
*vwrite,f1,f2,f3
%e, %e, %e
