Hi all, I am trying to understand the mesh decomposition and parallelism in libmesh. The mesh (is a SerialMesh) is a triangular surface mesh with total number of nodes: 1612, elements: 3144. Decomposition on 4 processors results in (got with n_local_nodes() and n_local_elem())
processor 0: nodes=430, elems=768 processor 1: nodes=395, elems=768 processor 2: nodes=393, elems=768 processor 3: nodes=394, elems=768 The questions I have are (1) The nodes on the decomposition boundaries seem not to duplicate on all processors which have elements use those nodes. Is that correct? (2) For a given element on some processor, How can I know which node is on this processor and which is on another? (3) How libmesh use ghost? ghost on nodes or elements?
