For real life geometries it is important to decrease the calculation time in order to optimize your simulation efficiency. This can be done by running simulations on multiple cores of a given computer in parallel. In this [https:// www.youtube.com/watch?v=uBIvhhtdHlg video] you will learn the idea behind parallelization, what you have to do to be able to run your simulation in parallel and how to postprocess such cases. In particular we will take a look at

• understanding paralellization
• steps of parallelization
• case setup
• visualization of decomposition
• running the case
• postprocessing
