Extract the mesh boundary for boundary condition handling or as a separate mesh. Convert a mesh consisting of any of the fore-mentioned n-dimensional linear elements to their second-order counterparts. Convert Quad4, Quad8, Quad9 to Tri3, Tri6. Add infinite elements to a volume-based mesh, handle symmetry planes. 
Build circles/spheres out of Tri3, Tri6, Quad4, Quad8, Quad9, Hex8. Build equispaced n-cubes out of Edge2, Tri3, Tri6, Quad4, Quad8, Quad9, Hex8, Hex20, Hex27. Refine or coarsen a mesh: prescribed, level-one-compatible, or uniform. Los Alamos National Labs GMV format (.gmv). Amtec Engineering's Tecplot ascii format (.dat). Amtec Engineering's Tecplot binary format (.plt). Sandia National Labs ExodusII format (.exd). Ideas Universal (UNV) format (.unv) with support for reading nodal data from 2414 datasets. 
Adding a new solver interface is as simple as deriving from these classes. The SparseMatrix, NumericVector, and LinearSolver allow for transparent switching between solver packages.Eigen (optionally LASPACK) provides iterative solvers and preconditioners for serial applications.Complex values are supported with PETSc.PETSc and Trilinos interfaces provide a suite of iterative solvers and preconditioners for serial and parallel applications.The code you debug and verify on small 2D problems can immediately be applied to large, parallel 3D applications.
Operators are defined to allow the same code to run unmodified on 2D and 3D applications. Vector-valued elements (Lagrange-Vec, Nedelec first type). Discontinuous elements (Monomials, L2-Lagrange). 6 and 12 noded infinite prisms ( InfPrism6, InfPrism12). 8, 16, and 18 noded infinite hexahedra ( InfHex8, InfHex16, InfHex18). 5, 13, and 14 noded pyramids ( Pyramid5, Pyramid13, Pyramid14). 6, 15, and 18 noded prisms ( Prism6, Prism15, Prism18). 4 and 10 noded tetrahedra ( Tet4, Tet10). 4 and 6 noded infinite quadrilaterals ( InfQuad4, InfQuad6). 4, 8, and 9 noded quadrilaterals ( Quad4, Quad8, Quad9). 
2, 3, and 4 noded edges ( Edge2, Edge3, Edge4). Hilbert and Morton-ordered space filling curves. Metis K-Way weighted graph partitioning. Development began in March 2002 with the intent of providing a friendly interface to a number of high-quality software packages that are currently available.Ī major goal of the library is to provide support for adaptive mesh refinement (AMR) computations in parallel while allowing a research scientist to focus on the physics they are modeling. The libMesh library is a C++ framework for the numerical simulation of partial differential equations on serial and parallel platforms.
