Is it possible to model a dynamics positioning (DP) system in aqwa??

      Dear Ansys,

      I want to know if it is possible to create a model with a DP system. My objective is to study vessel exursion and plot the graph against worst sea condition. This way i can evaluate the limiting criteria with current offshore standard (DNV GL, ABS, API). Appreciate if someone in ANSYS can clarify this. Thank you

      Hello Nas,
      the external user force is probably the best approach for you to implement (in python) a PID controller.
      There is an example of the external user force in your installation (under v\aqwa\utils\ExternalForceCalculation). You will find further details in section 30.3.1 of the user's manual.
      I hope this helps.
      Kind regards Ingrid
