[Libmesh-users] MatSetOption error

Hi All, I am building a network of 1-d EDGE2 elements embedded in 2-d or 3-d. At any given node of the network, it may have more than 2 elements intersecting. To enforce continuity of flux at such nodes, I have to add a constraint relating the dofs of intersecting elem

Hi, I pulled and built libMesh after a long time (~2 years) recently and noticed that the new implementation of PetscDM does not work with DirichletBoundary class anymore. Anytime I try to set the dirichlet BCs for the problem when running with petscdm (i.e. using SNES types vinewtonrsls or vin
