The hydrodynamic properties of the integration structures are sensitive to their relative locations defined in the Hydrodynamic Diffraction analysis.  In the time domain analysis, the relative positions between the program selected pairs of the diffraction panels of adjacent structures are checked and are not permitted to excess certain criterions.

If you cannot avoid this problem, and want the analysis to be carried out, you could define the debugging option in the time domain analysis input data file, such as   

If you are running Hydrodynamic Response (time domain analysis) in Workbench, you could use the pre-solve command (5.9.1. Specifying External Pre- or Post-Solve Operations) to run the python script for adding these terms into the input data file of (your project)\dp0\AQW-1\AQW\AQ\Analysis\TimeResponse.dat
