# DelFEM2
DelFEM2 is a end-to-end framework for geometry processing and FEM simulation covering wide range of components including shape editing, meshing, FEM simulation, linear solver, variational mesh deformer, and visualization. DelFEM2 is aiming to be an interactive digital engineering and authoring tool.
**There is a python binding available at**
+ [PyDelFEM2](https://github.com/nobuyuki83/pydelfem2) (deprecated)
+ [delfem2-python-bindings](https://github.com/nobuyuki83/delfem2-python-bindings) (maintained)
The implementation is based on my old open source project [DelFEM](https://github.com/nobuyuki83/DelFEM) library

# Install
No installation is necessary to use DelFEM2. All the source code of DelFEM2 can be download using git using the following command:
```
git clone https://github.com/nobuyuki83/delfem2.git
```
DelFEM2 can be compiled either as a header-only library or as a static library. Nothing complicated is necessary if DelFEM2 is used as a header only library -- just by include header files. To use DelFEM2 as a static library, you may compiles the delfem2 codes with option ```DFM2_STATIC_LIBRARY``` and several dependent DelFEM2 source files and link them manually (this is not very complicated too).
### Dependency & Binding
DelFEM2 does not have **any** external dependency. However, for some functionality such as OpenGL or Unit Test, you many need to download dependent repositories and compile them together.
Currently DelFEM support binding to the following C++ open source projects.
- glfw
- glad
- cereal
- alembic
- googletest
- cnpy
- zlib
- imgui
- tinygltf
- stb
One can download **all** the dependent C++ repositories with
```bash
git submodle update --init
```
This command downloads all the external third party codes into the directory ```delfem2/3rd_party``` (This operation might take few minutes). Or, one can download a specific dependent repository one-by-one with command
```bash
git submodule update --init 3rd_party/
```
