A parallel algorithm for the simulation of wave field in 3D heterogeneous media with a curved free surface is proposed. In this paper we use a mapping method to transform the initial problem. It is based on the construction of a curvilinear mesh that conforms with the geometry of the free surface in the domain of interest. This domain is then to be mapped onto the “calculation” rectangular domain covered with a regular mesh. Therefore, now we have the initial problems restated in generalized coordinates but in the domain of simple geometry. To solve the transformed problem in the “calculation” domain, we use a finite difference method. Numerical tests were carried out on the SSCC cluster of SB RAS. The results of numerical simulation are presented |
