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 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.
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:

  make -f Makefile.<compiler>.<os>

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:

  make -f Makefile.<compiler>.<os> clean

To delete the basicmod library, its .mod and object files, execute:

  make -f Makefile.<compiler>.<os> cleanlib

As a library

The command to execute in the terminal or Command Window is slightly different from the previous one:

  make -f Makefile.makelib.<distribution>.<compiler>.<os>

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:

  make -f Makefile.makelib.<distribution>.<compiler>.<os> clean

To delete the FEconv (and basicmod) libraries, the .mod and the object files, execute:

  make -f Makefile.makelib.<distribution>.<compiler>.<os> 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.

As a library

Please inspect the folder testlib/ to see an example of library use.
