I want to output "Total and Additional Loads" and internal forces on mooring lines (L#N@), but I don't know how to get node numbers. Thank you to whoever answer my question. |

Hi @YuYuJou, MoorDyn has updated from using Con to Point for describing point objects. However, to answer your question, POINT1FX and LINE1N51FX should be very similar. There might be minor differences depending on how / if you have point hydrodynamics. The motion of Point 1 and Line1N51 will be identical. The MoorDyn documentation has some more information about available output channels: https://moordyn.readthedocs.io/en/latest/inputs.html#id5 If you want the internal forces at every node along the line, you can add flags to the outputs column of the lines list: https://moordyn.readthedocs.io/en/latest/inputs.html#id3 |

I output "L3N50pz" and it worked. |

Hi @YuYuJou, I don't see that same error when I try to replicate things on my end. L3N50fz is a valid output string. A couple points to check: Are you using the most recent release of OpenFAST? What is the exact error that MoorDyn produces? What does your entire MoorDyn input file look like when the error is shown? |

Ah, that makes sense. There have been a number of improvements to MoorDyn since v3.3.0, and the MoorDyn docs reflect the current MoorDyn features in the most recent release (or sometimes the dev branch). If you want to get the segment tensions, you should be able to in v3.3.0 by proving the t flag in the line list output flags. |
