WavES (Wave Equations Solutions) is a combined theoretical and practical tool for the numerical solution of different types of time-dependent Wave Equations (acoustic, elastic and electromagnetic). Theoretical tool consists of published books, papers, courses and presentations where are presented new efficient numerical methods and strategies for the solution of time-dependent wave equations. Practical tool is represented by the C++ program library WavES for the computational solution of time-dependent wave equations (acoustic, elastic and electromagnetic) using three different methods: Finite Element Method (FEM), Finite Difference Method (FDM), Hybrid FEM/FDM method.
