MFEM is a free, lightweight, scalable C++ library for finite element methods that features arbitrary high-order finite element meshes and spaces, support for a wide variety of discretizations, and emphasis on usability, generality, and high-performance computing efficiency. MFEM team 4.7 2024-05-07 BSD: Free Linux, Unix, Mac OS X, Windows ...
The extended finite element method (XFEM) is a numerical technique based on the generalized finite element method (GFEM) and the partition of unity method (PUM). It extends the classical finite element method by enriching the solution space for solutions to differential equations with discontinuous functions.
These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM). Elmer comprises several different parts: [ 4 ] ElmerGrid – A mesh conversion tool, which can be used to convert differing mesh formats into Elmer-suitable meshes.
The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at
Finite Element Methods are techniques from numerical analysis for solving partial differential equations. Subcategories This category has the following 4 subcategories, out of 4 total.
The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration.It is common to use the finite element method (FEM) to perform this analysis because, like other calculations using the FEM, the object being analyzed can have arbitrary shape and the results of the calculations are acceptable.

Finite element model data post-processing is a paradigm for transforming the often highly detailed and complex outputs of Finite Element Method (FEM) calculations into a format that is easily understood by the user. The outputs from post-processing may be used in engineering judgements or analysis, as part of validity/functionality checks on ...
