Hello everyone, in OpenFOAM preCICE Delii’s fluid structure coupling, I can use OpenFOAM parallel computing coupling, but based on the official dealii adapter, I don’t know how to implement multi-core parallel computing. May I ask if there are any tutorials or detailed steps? Could you please give me some guidance? Thank you all

There are already coupled deal.II variants supporting parallelism. I would recommend you to [read the tips of the configuration page](https://precice.org/adapter-dealii-configure.html). If that’s still not enough and you would like to parallelize a deal.II code yourself, I can warmly recommend the [official deal.II tutorial collection](https://dealii.org/current/doxygen/deal.II/Tutorial.html) including plenty of resources on how to parallelize code. There are even [complete video lectures](https://www.math.colostate.edu/~bangerth/videos.html) (also linked from the deal.II webpage) explaining parallelization concepts in deal.II and beyond. I hope this helps.
