I’m setting up a new FASTLink model. Latest version from here: orcina.com/Support/
I am getting the following error: The user-defined platform added mass matrix is unsymmetric. Make sure PtfmAM returned by UserPtfmLd<> is symmetric. Aborting FAST.
I can’t seem to spot the differences between my earlier FASTlink models. Bar updated version of OrcaFlex v10.1, and a slightly different set up: New AQWA model etc, mooring lines etc. The set-up process seems to be the same.
Any help would be greatly appreciated
