This change has been made in the interests of consistency across the program. The line type CG offset data has been renamed as centre of mass.This may be more appropriate for a line embedded in the seabed, as applying the force at the contact point might lead to unphysical twisting of the line. An option has been added to allow seabed contact forces to be applied at the line centreline when torsion is included, rather than at the point of contact. ![]() This model does not average the lateral and axial friction coefficients and instead treats them as defining independent forces. A decoupled model of lateral and axial friction has been added for seabed interaction.The term normal friction coefficient has been replaced by lateral friction coefficient to match the prevalent convention in the literature and avoid confusion with the seabed normal direction.These provide new modelling options for the interaction between the line and the soil, and may be used for applications such as pipeline breakout or slip. ![]()
