Parallelization - depthCharge

2D scalar transport


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 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 post process such cases. In particular we will take a look at

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