About FreeFem

FreeFEM is a partial differential equation solver for non-linear multi-physics systems in 2D and 3D using the finite element method.

What's new in 4.15

Important changes:
- FreeFEM can now run Markdown (.md) files as well as .edp files. Markdown can be used to document your FreeFEM scripts (see for example the .md files in the examples/examples directory). When running a .md file, FreeFEM will execute the code contained in the FreeFEM code blocks, delimited by
freefem
[freefem code]

Documented Markdown examples in the distribution can be viewed on the documentation website (toggle Search in examples). Markdown can be previewed with e.g Visual Studio Code, with the FreeFEM VS Code extension providing syntax highlighting for FreeFEM code blocks.
- add command md2edp to extract freefem code form Markdown file.
- PETSc 3.22.2
- move the plugin msh3 in kernel , so remove all load "msh3" in all examples and .idp files
See CHANGELOG 4.15 for more detail
