A Problem on Using Openfoam and Dealii Parallel

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. 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 including plenty of resources on how to parallelize code. There are even complete video lectures (also linked from the deal.II webpage) explaining parallelization concepts in deal.II and beyond. I hope this helps.
