The structures’ orders have no effect on this issue if they are in a hydrodynamic interation structure group. From the error message, the simulation stopped as TIME=0.0, I guess that your joint definition may not be correct, which may connect the wrong structures together.
Please use (your Ansys installation folder)\aqwa\bin\winx64\ags.exe to open your Aqwa model (in your project\TimeResponse.res), which may help you to check the connections between the structures. For example, the structure sequence numbers and the articulation sequence numbers can be displayed in Ags as shown below
You can also display the Hydrodynamic Diffraction model (in your project/ANALYSIS.RES) by ags.exe to check if the relative locations of the structures in HD analysis and HR analysis are the same.
