What is the blog?

This blog is a re-interpretation of the tessendorf.org website I had for several years. At the moment I am putting up the papers and reports page. Eventually I will put up the other pages on frumple and old Arete Image Software materials. You can also find this information at my university page

eWave: Using an Exponential Solver on the iWave Problem

Jerry Tessendorf
March 2014
Technical Note
The iWave approach to simulating surface waves is fast and efficient, but suffers stability and artifact problems. By rephrasing the algorithm to employ two first order diffential equations for the displacement and velocity potential, and using an exponential solver, much more accurate simulations result. Importantly, the solution is free of the stability and artifact issues of the previous approach, and maintains high efficiency and flexibility.
