Version 6.1S
WAMIT Version 6.1S extends the first-order (linear) capabilities of WAMIT® to include the complete second-order nonlinear analysis. The extended capabilities of V6.1S include:
Sum- and difference-frequency components of the second order forces and moments.
The second-order forces/moments can be evaluated both by direct and indirect approaches
Sum- and difference-frequency components of the second-order hydrodynamic pressure on the body surface.
Sum- and difference-frequency components of the second-order hydrodynamic pressure in the fluid domain
Sum- and difference-frequency components of the second-order wave elevation on the free surface.
Sum- and difference-frequency components of the second-order Response Amplitude Operator (RAO)
All of the second-order quantities are evaluated in the presence of bichromatic and bidirectional waves and one or more structures.
The structures can be either freely floating, constrained or fixed.
A demonstration version of V6.1S with predefined geometry inputs is available. Send your request to info@wamit.com.
