load of mooring line


Could anyone tell me how to get loads of the mooring lines from FAST 8 ?
The model I used is OC3Hywind, I didn’t find any information about the mooring line load from the User’s Guide.

Many thanks,

Dear Cheng.Zhang,

I assume you are using Test24 from the FAST v8 CertTest, which is a model of the NREL 5-MW turbine atop the OC3-Hywind spar. This model uses MAP++ to model the mooring system (quasi-statically). In MAP++, the mooring line fairlead and anchor tensions can be output by specifying the “tension_fair” and “tension_anch” flags in the MAP++ input file (in fact, they are already set in the Test24 example, and so, these line loads are already written to the output file of Test24).

Best regards,

Dear Jason,

Thank you!
I found that T and T_a in the outlist represent fairlead force and anchor force respectively. It is always there, but I never take notice of them… :blush:

Best regards,
