Hello, I'm working with a FE-Software where I get out the element stiffness matrices and the element-node correspondency to setup the stiffness matrix for solving with PETSc.
I'm currently fighting with the interface definition. My LocalToGlobalMapping for test-purposes was the "identity"-IS, but I guess this is far from the optimum, because nowhere is defined a node set of interface nodes. How do I declare the interface? Is it simply a reordering of the nodes, the inner nodes are numbered first and the interface nodes last? Thank you in advance ando -- /"\ Grassl Andreas \ / ASCII Ribbon Campaign Uni Innsbruck Institut f. Mathematik X against HTML email Technikerstr. 13 Zi 709 / \ +43 (0)512 507 6091
