# [Legacy module](@id legacy_module)
|
||
|
|
|
||
|
|
JuliaFEM.jl is **0.x**; the default `using JuliaFEM` surface is the type-stable
|
||
|
|
pipeline described in `AGENTS.md` (`Element{K,P,S,N}`, `DOFHandler`, domain
|
||
|
|
kernels, modern assemblers).
|
||
|
|
|
||
|
|
Older tutorials, notebooks, and helper scripts target a **previous** API:
|
||
|
|
`Problem` / `Assembly` / `Solver` / `Analysis`, Dict-based fields, legacy element
|
||
|
|
constructors, and some mesh readers (for example Abaqus `.inp` and Code Aster
|
||
|
|
`.med`). That code lives under `src/legacy/` inside `module Legacy`.
|
||
|
|
|
||
|
|
## Enabling Legacy
|
||
|
|
|
||
|
|
Set the environment variable **`JULIAFEM_ENABLE_LEGACY=1`** before the first
|
||
|
|
`using JuliaFEM` in a Julia session so the `Legacy` submodule is loaded.
|
||
|
|
Symbols are namespaced as `JuliaFEM.Legacy.<name>` and are **not** re-exported
|
||
|
|
from `JuliaFEM`.
|
||
|
|
|
||
|
|
## When to use it
|
||
|
|
|
||
|
|
- Porting old scripts or reproducing historical results.
|
||
|
|
- Reading meshes or models that still depend on legacy constructors.
|
||
|
|
|
||
|
|
For new work, prefer the current API and the Quarto site map at
|
||
|
|
`juliafem.github.io/docs/documentation-map.md`.
