Program feconv is an utility to convert between several mesh and FE field formats, like ANSYS mesh files (.msh), MD Nastran input files (.bdf), I-Deas Universal (.unv), VTK files (.vtk), etc. If you use a Modulef format to store an intermediate mesh (.mfm). It can transform the FE type of a mesh composed of trangles or tetrahedra, to Lagrange P1 or P2, Raviart-Thomas (face) or Whitney (edge) finite elements. It also uses third-party code to perform bandwidth optimization (CutlHill-McKee optimization).

README
# 1. Description
FEconv can convert finite element (FE) mesh written in several commercial file formats. It can also transform the FE type and/or perform some bandwidth optimizations. Some conversion capabilities are also present for mesh fields. Please type `feconv -h` and see EXAMPLES section to know more details, or visit the [FEconv help webpage](http://victorsndvg.github.io/FEconv) for more information.
# 2. Installation
## As a standalone program
The prerequisites are:
- The program _make_ (for Windows it can be found as _mingw32-make_ in the MinGW distribution).
- A Fortran 2003 compiler. At the present time, only the GNU Fortran compiler, _gfortran_, and the Intel Fortran compiler, _ifort_, are supported.
After install the prerequisites:
- Go to the [FEconv webpage](https://github.com/victorsndvg/FEconv).
- Download the compressed file and uncompress it in the installation folder.
- Open a terminal in Linux or Mac OS X, or a Command Window in Windows, go to the installation folder and type:
```shell
make -f Makefile..
```
where
- _<compiler>_ can be _gfortran_ or _ifort_.
- _<os>_ can be _linux_, _windows_ or _osx_. For Mac OS X, some Makefiles are provided, indicating which version they were tested for. Be aware that in Windows, MinGW distribution can use _mingw32-make_ instead of _make_.
To delete the FEconv executable, its .mod and object files, execute:
```shell
make -f Makefile.. clean
```
To delete the basicmod library, its .mod and object files, execute:
```shell
make -f Makefile.. cleanlib
```
## As a library
- The command to execute in the terminal or Command Window is slightly different from the previous one:
```shell
make -f Makefile.makelib...
```
where _<distribution>_ can be _static_ or _dynamic_.
The library and the .mod files are automatically moved to folders _lib/_ and _include/_, respectively.
When compiling for several compilers, clean the object files:
```shell
make -f Makefile.makelib... clean
```
To delete the FEconv (and basicmod) libraries, the .mod and the object files, execute:
```shell
make -f Makefile.makelib... cleanlib
```
# 3. Usage
## As a standalone program
Please execute `feconv -h` to see the command line options and some examples of use, or visit the [FEconv help webpage](http://victorsndvg.github.io/FEconv).
## As a library
Please inspect the folder _testlib/_ to see an example of library use.
