This is an an implementation of the third-order, directionally-spread, irregular wave theory of Madsen and Fuhrman (2012), with corrections as indicated in the appendix of Fuhrman et al. (2023). Any publications in which results from this code are used are kindy asked to please cite both of these works appropriately.


The code provided can compute both free surface elevations and kinematics for irregular waves to a desired order (1, 2 or 3). Several examples demonstrating its full use can be found in the Examples folder, which are intended as self explanatory. These include some regular, as well as irregular, wave examples, including time series generation, surface elevation maps, as well as wave kinematics. All source code used by these examples can be found within the Source folder. As a first example, it is suggested to execute e.g. the example_ThreeWaves.m script, which confirms the coefficient values in Tables 2 and 3 of Madsen and Fuhrman (2012).
