Computer Modelling in the National Center for Research and Application for Renewable Energy Sources

This contribution deals with using of computational engineering methods in research, design and development of devices used in the field of renewable and alternative power sources. Basic information about possibilities of computer modelling are given, mainly modelling and simulation multiphysical processes with the finite element methods as heat or mass transfer, conversion and acquiring energy. The paper shows also some examples of thermal and heat flow multiphysics solutions and flow analyses of liquid or gas and coupled field analyses, generally formulated for devices in power engineering, electrotechnics or lighting. In conclusion the future possibilities of usage of the methods are described.
