Fluid-memory model (Retardation function): comparison between convolution calculation and linear models
One approach to develop time-domain model of marine structure is using Cummins equations: (1) where is the generalized mass matrix, is the constant infinite-frequency added mass, is restoring coefficient, is the impulse response function usually referred to the retardation or memory functions, is the wave exciting force and ...
matlab codes of Fourier Transform and Inverse Fourier Transform. Examples are also provided.
Programming by S-Function Builder is an effective way to embed algorithms. There are many comprehensive examples/tutorials provided on Internet. Here, I just try to summarize the main points. The debugging method using Visual Studio will also be included.
Irregular wave generation based on PM spectrum was studied and codes for MATLAB were presented. The functions can be simply utilized for the simulation in Simulink using MATLAB function block.
