Abstract
The numerical solution of multidimensional nonlinear evolution equations, in which the field depends on several spatial coordinates, is considered. The work was based on the Fast Legendre Transform algorithm. A model for the numerical calculation of the processes of surface growth and the evolution of a two-dimensional velocity field, implemented in the MATLAB software environment, is presented. With the help of this model, the growth of regular surfaces and surfaces with a random initial shape (two-dimensional Gaussian noise with zero mean and unit variance) was considered, and the level lines and lines of discontinuities of the growing surfaces were also shown. The result of numerical simulation of a localized random velocity field with an initial field in the form of two-dimensional Gaussian noise with zero mean and unit variance is presented.
