Summary

The option to account for convolution-based hydrodynamic forces on Beam and Membrane components has been introduced to AquaSim. This implementation allows for including memory-effects that arise from frequency-dependent added mass and damping in time-domain simulations.

A test case demonstrates that including the convolution term can lead to a reduction in structural response and mooring loads under irregular sea states. Consequently, analyses performed without convolution may provide more conservative estimates.
