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).

feconv's Introduction

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.

feconv's Issues

vtu to mphtxt conversion not ending

Hi,

after outputting a Cleaver method mesh using 3D Slicer, every time I want to convert the vtu format mesh into mphtxt, the conversion in the terminal (Linux) or the power shell (Windows) goes on for days and it does not end at last.

Tried making the model as simple as possible like 120 KBs and still the same issue.
I have not found any solutions and have interchanged any option at hand but still no luck, would appreciate it if someone has an idea.

Cheers

Segmentation fault when converting ansys msh to unv

Hello all,
I am trying to convert an ANSYS .msh into a gsh .msh using a .unv intermediate file.
However when I run:
./feconv Barge_test/Barge.msh Barge_test/Barge.unv
The following error is returned:

 Space dimension: 3

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

What is happening? I ran the examples which worked without any issues.

Fluent msh format

Hello,
Thank you for this much needed utility, is there any plan for supporting the fluent msh mesh in the future?

test.unv does conform to the unv standard, the line containing "Workpiece" and "File written" should be treated as comment.

Note that each dataset begins with a delimiter and ends with a delimiter. Between datasets, the file can contain lines (for example, comments), which are not part of any dataset.

Trouble compiling FEconv on Windows with GFortran

Hi!

I would like to compile FEconv with GFortran (MinGW GFortran 7.1.0 64 bits) on Windows.
I encounter compilation errors that prevent me from getting final executable.

I have used CMake to generate executable

Could you have a look at my command line and at the errors I get?

When I will succeed in compiling the program, I will propose pull requests to have continuous integration.

Here are my log infomations:

Dear authors,

Please, publish a release of your wonderful converter with attached binaries for Linux and Windows. Users do not want to compile anything.

VTU to UNV not working

Hi,
I've tried the converter and can not make it work. My test model is attached: vtu.zip
Command, I've used for the conversion, is: ./feconv default.vtu default.unv
The program infinitely runs and does not produce any output. Eats approximately 5% of CPU.
Please, what am I doing wrong?

"feconv" error

Hello,
I am trying to use feconv to change my mesh file format from .msh to .unv.
But after unzipping the directory, and running the make command in my mac, ( make -f Makefile.gfortran.osx-10.11-elcapitan), I get the following error every time I try feconv command:

$ feconv -gm examples/dt5.msh dt5.unv
-bash: feconv: command not found

even though "feconv" is generated in my directory after "make" command is run.
Any ideas what could have gone wrong in this process?

Comsol 5.3 Meshfile not readable

I tried a 2D Comsol mphtxt to convert into unv or msh files. Neither the -l listing is working.
I get errors like:

I tried with triangle, quad and mapped meshes and toggled the four options in export comsol:

Nothing works.
Any help?
feconv.exe compiled with gfortran in Cygwin.

Ansys mesh examples file give segfault

Thank you for the nice library.
I am in Windows with Msys2, with mingw64 terminal. The version of the gcc toolchain is the 13.2.0 https://packages.msys2.org/base/mingw-w64-gcc. I compiled feconv through the command:
mingw32-make.exe -f Makefile.gfortran.linux and the compilation seems ok. I've tryed some of the examples in the folder and the conversion works, but it seems for all the cases where the input file is an Ansys .msh the conversion fails with a segfault. For example:

$ ./feconv examples/ansys_mesh.msh output.unv
Space dimension: 3
Reading zone 1: Vertex
Reading zone 2: Triangle, Lagrange P1
Reading zone 3: Tetrahedron, Lagrange P1

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Any clue why this happen?

Thank you,

Convert GMSH .msh to ANSYS .msh

Hello,

Using the following command ./feconv -gm input_GMSH.msh output_ANSYS.msh results in the program running for very long but does not output anything. This is in ubuntu 20.04.

Thanks,

Peter

unv 2414 not working?

Hi!

Great work, really an impressive effort you have put in! I have been looking around for a thing like this for a long time!

I am trying to get a file in unv-format to vtu, mesh works fine but I get some strange error for 2414 (and also for 55).

I this known to you, or perhaps I am missing something?

The files are tests I made, one with 2414 and one with 55.

test2.unv.txt
test3.unv.txt
