This document describes the theoretical basis and validation of the membrane load formulation Regular net in AquaSim. This load formulation is based on the cross-flow principle, where the fluid velocity relative to the membrane panel is decomposed into a normal- and tangential component.

This document presents three new parameters for impermeable load formulations “Lice skirt” and “Closed compartment”, as well as the removal of the parameters “Bottom factor” and “Vacuum surface suction” previously used for the load formulation “General impermeable net”.

This technical note presents the theoretical formulation and implementation of Stokes (regular) waves in AquaSim. The document focuses on the fifth-order Stokes wave theory, which provides a representation of nonlinear, periodic surface gravity waves for waves of moderate to high steepness.

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.

This document presents the hydrodynamic parameters and modelling assumptions for the Surface Tarpaulin load formulation in AquaSim. It explains how impermeable membrane panels at the water surface interact with waves and current. This document aims to clarify how key coefficients affect drag -, suction-, added mass- and damping forces.
