Elmer
Elmer is an open
source multiphysical simulation software developed by CSC. Elmer
development was started 1995 in collaboration with Finnish
Universities, research institutes and industry.
Elmer includes physical models of fluid dynamics, structural
mechanics,
electromagnetics, heat transfer and acoustics, for example. These are
described by partial differential equations which Elmer solves by the
Finite Element Method (FEM).
Elmer
has a modern programmable graphical user and preprocessing interface.
It provides a large selection of modern numerical methods
(see below)
Features include:
- The Elmer package contains solvers for a variety of
mathematical models
- Heat transfer: models for conduction, radiation and phase
change
- Fluid flow: the Navier-Stokes, Stokes and Reynolds
equations, k-ε model
- Species transport: generic convection-diffusion equation
- Elasticity: general elasticity equations, dimensionally
reduced models for plates and shells
- Acoustics: the Helmholtz equation
- Electromagnetism: electrostatics, magnetostatics,
induction
- Microfluidics: slip conditions, the Poisson-Boltzmann
equation
- Levelset method: Eulerian free boundary problems
- Quantum Mechanics: density functional theory (Kohn-Sham)
- Numerical methods:
- All basic element shapes in 1D, 2D and 3D with the
Lagrange shape functions of degree k ≤ 2
- Higher degree approximation using p-elements
- Time integration schemes for the first and second order
equations
- Solution methods for eigenvalue problems
- Direct linear system solvers (Lapack & Umfpack)
- Iterative Krylov subspace solvers for linear systems
- Multigrid solvers (GMG and AMG) for some basic equations
- ILU preconditioning of linear systems
- Parallelization of iterative methods
- The discontinuous Galerkin method
- Stabilized finite element formulations, including the
methods of residual free bubbles and SUPG
- Adaptivity, particularly in 2D
- BEM solvers (without multipole acceleration)
