Dear Dr.Jonkman
Greetings for the day!Thank you for your responses before. I just have quick question in Moordyn for OC3 Hywind model. I would like to add a clump weight at about 0.1L of the mooring line.Say if my mooring line length is 902 this is going to be approximately about 90m from fairlead. I have created ‘Connect’ which are described as intermediate points in all the three lines . Below is the moordyn file I have used.But am ending up with error message,I know there is a mistake in introducing the new connections for clump weight.I request you to kindly help me in catching it.
Thanks
Krishnaveni
