Massively parallel simulations in computational engineering are often carried out with Open Source software providing good scalability. These software do not usually come with nicely integrated pre- and postprocessors. Instead, the users often use a combination of different tools in different stages of the simulation. This course presents some widely used software for computational engineering for the different stages of the simulation. Emphasis on the course will be on the use of two versatile finite elements packages - FENiCS and Elmer - and on the visualization of the results. Both serial and parallel operation will be demonstrated. The course will be relevant for specialists working with R&D in computational engineering (electromagnetics, fluid dynamics, mechanics).Tentative agenda
