    OVERVIEW

    The course aims to provide a presentation of the most common partial differential equations (PDE) and their solution techniques through an analysis of various applications. The emphasis is devoted to second order PDE and the understanding of the specific techniques for elliptic, parabolic and hyperbolic cases.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Modeling and Simulation Fundamentals. Theory and Practice of Continuous Simulation and related Methodologies. Theory and Practice of Discrete Simulation and related Methodologies. Hybrid Simulation.

    AIMS AND LEARNING OUTCOMES

    Active participation in lectures and individual study will enable the student to:

    - be able to classify the main partial differential equations;

    - calculate the analytical solution of partial differential equations of elliptic, parabolic and hyperbolic types;

    - use the techniques of separation of variables, series and Fourier transform, special functions.

    TEACHING METHODS

    The module is based on theoretical lessons.
