  Dear all,
  
  To be able to adjust the frequency dependent motion system of floating bodies I want to recalculate the responses of two interacting floating bodies based on the hydrodynamic data calculated by AQWA. I use the data from the ANALYSIS.LIS file.
  
  However, when I recalculate the Response Amplitude Operators(RAO's) for the interacting bodies by myself it does not match with the RAO's given by AQWA. I make use of the equations written below:
  
  Regarding the hydrodynamic structure interaction matrices, (A12, A21 & B12, B21) I use the matrices given in the .LIS file listed as H/I ADDED MASS/DAMPING FOR FORCE ON STR# 1/2.
  
  However, I did not succeed so far the reconstruct the RAO's given by AQWA. Has anybody an idea what the problem could be?
  
  Regards
