Does anyone knows some good finite elements routines in 2D?
PerennialII said:Could you elaborate a bit, are you after something for a particular application, a general purpose code, open source codes, something to 'just' play around ...?
PerennialII said:Public domain with source are listed pretty good at :

bunch of them will do the job, suppose it's a question whether you want to work with a fairly complete package (like elmer for one, but am biased in recommending it ) or a code which is a short and simple one and will just do the job for your application.
Finite element routines in 2D are used to solve complex engineering and scientific problems by breaking down a 2D domain into smaller, more manageable elements. This allows for the accurate analysis of forces, stresses, and other physical phenomena in a given system.
Finite element routines in 2D use mathematical models to discretize a continuous 2D domain into smaller elements, usually triangles or quadrilaterals. These elements are then solved iteratively to obtain an approximate solution for the entire domain.
Finite element routines in 2D can be used to solve a wide range of problems in various fields such as structural engineering, fluid mechanics, heat transfer, and electromagnetics. Some applications include stress analysis of structures, fluid flow in pipes, and heat transfer in electronic devices.
Finite element routines in 2D offer several advantages, including the ability to handle complex geometries, the ability to model nonlinear behavior, and the ability to incorporate different types of boundary conditions. They also provide high accuracy and efficiency compared to other numerical methods.
One limitation of finite element routines in 2D is that they can be computationally expensive, especially for large and complex problems. They also require expertise in selecting appropriate element types, meshing techniques, and boundary conditions. Additionally, they may not be suitable for problems with discontinuities or singularities.
