More than 330 years later, it still had no direct numerical solution.
In 1971, that problem still had no direct numerical solution.
They are usually complex and require computers to help with numerical solutions.
We seek a numerical solution that exhibits the same behavior.
However, numerical solutions to any accuracy can be easily obtained.
Gnanadesikan et al. give numerical solutions for a few cases.
And then we can evaluate numerical solution at any location in physical domain.
For this a numerical solution can be used, taking small steps along the impermeable base.
However, the split-step method provides a numerical solution to the problem.
The numerical solution of the level set equation, however, requires sophisticated techniques.
