Re: gmsh and libscotchmetis
Hi, Adam! Sounds good, thanks. I notice you also added the interfaces you need for gmsh to Bug 506033, thanks. Ok, done. For Elmer, I noticed that it could do node-wise or element-wise partitioning, and just disabled the element-wise partitioning which used METIS_PartMesh* functions. Is it possible to do something similar for gmsh? I just shortly looked at the code, but it seems, that the functionality of metis-module will be seriously restricted, if those 2 functions will be disabled.

Re: gmsh and libscotchmetis
Just a guess, maybe we can contact metis upstream with the question of relicensing it under distributable license?

Anton Hi, last week I met gmsh guys They told me that they prefer to use metis instead of scotch because metis provides some multiconstraint partionning... It seems that scotch upstream has no plan to develop such features right now. So my feeling is that we shall disable metis support in the present version of gmsh or consider to make a gmsh-metis package which will goto to non-free as an alternative. This solution may be great as we can take full advantage of the latest gmsh developments.

Anton Hi, I've contacted metis upstream to ask permission to place it on debian mirrors, and also asked him to consider a different license: he agreed to put the sources and binaries on debian mirrors, but didn't answer about the relicensing; and since it wasn't the first time he was asked for this, I'm guessing he's not interested in changing the license. Anyway, if someone wants to try, it won't do any harm. I did the same about ten years ago... -- GPG fingerprint: D54D 1AEE B11C CE9B A02B C5DD 526F 01E8 564E E4B6 Engineering consulting with open source tools http://www.opennovation.com/ signature.asc Description: This is a digitally signed message part
