Why HOMARD is not open source?

Hi

Sorry if this is not a appropriate topic for this forum.

I was planning on learning how to use the HOMARD component for mesh refinement, but not being open source is very off putting for me.
Can someone please clarify why HOMARD is not open source and if there are any plans to make it open
source in the future?

Thanks

Re: Why HOMARD is not open source?

Hi,
I can not comment on the reasons as I have no insights,
but for simply using it, you don't need the source code.

Do you plan on adding new features or doing other developments?

Best,
Richard

I don't plan on adding new features for now, but I'm switching  to code_aster from propietary solutions because I belive in the benefits of open source technology: freedom, flexibility, quality, control, continuity...

Adding a closed source component to a set of very high quality tools seems odd to me. For now, I prefer to
not invest time in learning HOMARD until I understand what his plans are concerning this issue.

I just checked the Homepage of the Homard project. It seems that they changed their license just recently to LGPL
See: code-aster.org/outils/homard/en/index.html#licence

I think that referes to the salome module to link code aster with homard, but the software itself is proprietary:
code-aster.org/spip.php?article306

I double checked the page refers to Homard, and the version which is in current aster full and salome is still version 11.7 (which has the free use with aster exclusively) while the documentation already refers to 11.8. So there is hope that the next release will be LGPL.

Of course an official statement would be better.

Re: Why HOMARD is not open source?

Sorry for the delay.
I do confirm that HOMARD is free LGPL. You can use it either with the SALOME platform or code_aster, with no restriction.
With SALOME, HOMARD is driven by the GUI or by python. An extensive description is given by the "help" button, including tutorials and examples.
With code_aster, the command is MACR_ADAP_MAIL (documentation U7.03.01). Some test cases are implemented.

The two following papers are available:
    G. Nicolas, T. Fouquet, S. Geniaut, S. Cuvilliez, Improved Adaptive Mesh Refinement for Conformal Hexahedral Meshes, Advances in Engineering Software, Vol. 102, pp. 14-28, 2016, doi:10.1016/j.advengsoft.2016.07.014
    G. Nicolas and T. Fouquet, Adaptive Mesh Refinement for Conformal Hexahedral Meshes, Finite Elements in Analysis and Design, Vol. 67, pp. 1-12, 2013, doi:10.1016/j.finel.2012.11.008

Please contact me if you need more information.

Thanks for the clarification and the information. An update in the code_aster licenses page may clarify confussion in the future:
