Elmer FEM solver
Elmer is an open source finite element software for multiphysical problems
|
adaptive | Module for adaptive meshing routines. The adaptivity is based on solver-specific error indicators that are used to create a field with the desired mesh density. This may be used by some mesh generators to create a more optimal mesh |
bandmatrix | Module defining utility routines & matrix storage for band matrix format. This module is currently of no or, only little use as the default matrix storage format is CRS |
bandwidthoptimize | Module for reordering variables for bandwidth and/or gaussian elimination fillin optimization. Also computes node to element connections (which implies node to node connections, and thus the global matrix structure) |
blocksolve | Module for solution of matrix equation utilizing block strategies |
clusteringmethods | Module containing various clustering methods that may be used in conjunction with algebraic multigrid methods, for example |
coordinatesystems | Module defining coordinate systems |
crsmatrix | Module defining utility routines & matrix storage for sparse matrix in Compressed Row Storage (CRS) format |
defutils | Module containing utility subroutines with default values for various system subroutine arguments. For user defined solvers and subroutines this module should provide all the needed functionality for typical finite element procedures |
differentials | This module contains some built-in material laws, and also some vector utilities, curl, dot, cross, etc. Some of these may be of no use currently |
diffuseconvective | Diffuse-convective local matrix computing in cartesian coordinates. Used by a number of solvers |
diffuseconvectivegeneral | Diffuse-convective local matrix computing in general euclidian coordinates |
directsolve | Module containing the direct solvers for linear systems given in CRS format. Included are Lapack band matrix solver, multifrontal Umfpack, MUMPS, SuperLU, and Pardiso. Note that many of these are linked in with ElmerSolver only if they are made available at the compilation time |
dxfile | |
eigensolve | Module containing ARPACK routines for the solution of Eigenvalue problems |
elementdescription | Module defining element type and operations. The most basic FEM routines are here, handling the basis functions, global derivatives, etc.. |

exchangecorrelations | This module contains different parametrizations for the exchange-correlation energy density (function exc(r,s,ixc) and the function uxc(r,s,ispin,ixc) calculating the corresponding exchange-correlation potential. Here r is the electron density, s is spin density and ixc is one of the integer parameters |

linearalgebra | Linear Algebra: LU-Decomposition & matrix inverse & nonsymmetric full matrix eigenvalues (don't use this for anything big, use for example LAPACK routines instead...) |
