Input file for foammooring

harishameed33 · April 30, 2024, 09:40

Hi,

I am using foammooring coupled with OpenFAOM to simulate the OC5 floater. the mooring data is given in literature which also specifies Equivalent mooring line extensional stiffness as 753.6 × 10^6 N/m. But i am not sure where to put the stiffness value in the inputfile. There is EA in Newton and bottom stiffness (pa/m). but i am not sure if this value goes here. can anyone guide me on this.

This is the link for the reference paper that has these properties. [Paper Link]

hello Haris Hameed,
you can check the official introduction here:https://moordyn.readthedocs.io/en/la...nputs.html#id2

which says EA is the line stiffness, product of elasticity modulus and cross-sectional area (N).

BTW, could you tell me what's the vaule of your dtM? i set the dtM as the official instruction(same with the openfoam case delta T), but it comes out with error.
