Open dynamic_01.avz in AquaView. The analysis may not have converged for all steps, in such cases you are notified with the message as shown below.

Accept this message by selecting OK. You will then be able to access the results in AquaView. Plot axial forces from Result > Local section forces > Axial forces [N]. Start the playback and watch how the beam and the trusses displace when current and waves passes.

In this figure the axial force in the lower most element of Rope 1 is plotted. You can get an indication of how the roller works by watching how the element is lengthened and shortened as a result of beam response. Comparison of axial forces between element A and B of the two rollers also provides an indication of how the roller adjust the lengths to meet the Tolerance criteria set in AquaEdit.
