Thank you very much! If I do not use "adaptive coarsening", just only use mesh data structure. Whether parallel mesh can work with 10K CPUs?

In practice, ParallelMesh currently has bugs with adaptive coarsening, which means that none of the main developers regularly use it, which means that it's likely to have other bugs that just haven't been found yet. With SerialMesh you're probably not going to scale well past a few thousand CPUs, less depending on your application. > In addition, where can I find more detail manual about how to use > parallel mesh? For applications written to not assume local access to non-semilocal elements, simply creating a ParallelMesh and using it the same way as you would a Mesh should be sufficient. --- Roy ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
