Technical Approach

Advanced Numerical Methods

NVSolve employs cutting-edge numerical techniques to solve complex marine engineering problems with high accuracy and efficiency.

Boundary Element Method with Higher Order Elements

NVSolve implements an advanced Boundary Element Method (BEM) using higher order elements for superior accuracy in hydrodynamic analysis. Unlike traditional constant panel methods, our higher order BEM provides:

  • Improved convergence rates with fewer elements
  • Better representation of curved geometries
  • Higher accuracy for the same computational cost
  • More precise calculation of hydrodynamic coefficients

Irregular Frequency Suppression Techniques

Irregular frequencies can cause numerical instabilities in boundary element solutions for marine structures. NVSolve implements two advanced suppression techniques:

CBIEM (Coupled Boundary Integral Equation Method)

Couples interior and exterior domain solutions to eliminate irregular frequencies, providing smooth response curves across all frequency ranges without numerical artifacts.

EBIEM (Extended Boundary Integral Equation Method)

Extends the boundary integral formulation with additional terms that naturally suppress irregular frequencies, resulting in more accurate hydrodynamic coefficients.

These techniques ensure reliable results even at frequencies where traditional BEM solutions would exhibit unphysical spikes or oscillations.

Fourier-Kouchin Theory for Free-Surface Hydroelasticity

NVSolve implements the advanced Fourier-Kouchin Theory to accurately model hydroelastic interactions between flexible structures and free-surface waves. This approach:

  • Captures the coupled dynamics between structural deformation and fluid motion
  • Accounts for free-surface effects on flexible floating structures
  • Provides accurate prediction of wave-induced structural responses
  • Enables analysis of complex hydroelastic phenomena like springing and whipping

Mathematical Foundation

The method employs Fourier transforms to convert the spatial domain into the wavenumber domain, allowing efficient solution of the coupled fluid-structure equations while satisfying free-surface boundary conditions.
