Hmm--I ran the analysis, changing the frequency from 1 to 50 Hz and got 
very different results for each case, sort of like I'd expect. It looks 
like the only issue is that you need to scan over a lower range of slip 
frequencies. For your model, most of the interesting stuff seems to be 
going on at below 1 Hz slip freq.
