I am wondering a problem about unkown varialbes (x) distribution in libmesh. Practically, you use finite element method to solve PDE, you will finally get the linear equation Ax=b. In libmesh, if you solve it parallelly, you need to first partition the domain, that is A is partionted. However, each node in the cluster has all the variables x or only the part of x? Could you give me some advice? thanks a lot.

Regards,
