I think the wiki Roadmap have to be changed…
FEM is current development. The Future is now :D

I will have a look at the code, for sure :mrgreen: . I'm curious how you guys implemented the contact :geek: . I promise I do not do any comments in this regard at the moment 8-)

I'm curious how you guys implemented the contact :geek:
Ruan made us mechanical engineers a nice C++ template on howto add a constraint.(see attached)
Ofentse who had some complex contact modelling in his thesis (which was done with Calculix) added this using the template only knowing Python in about a week.

No doubt :o The progress makes me dizzy :lol:
Hope your doing well. Not asking to do anything, can you explain the status of the copr builds, I see them chugging along. Do they have Netgen support? Have you seen the OCCT7, SMESH7, VTK7, Netgen5.3 etc discussions? How much do the Fedora package managers handle this. How much does FreeCAD have to do.

/Off topic/
Thanks! I'm OK, but I have very little time for FreeCAD. I did a quick scan of what's happening, but no time to read in details. I fixed the fedora builds yesterday. The latest one is OK except fedora 24 [1]
Those are pure master builds, so no extra patches included. I can switch on whatever we need to switch and whatever works on fedora. Currently there are only 2 switches + some for handling directories:

Code: Select all

       -DFREECAD_USE_EXTERNAL_PIVY=TRUE
       -DFREECAD_USE_EXTERNAL_SMESH=TRUE
If there is anything that works on fedora and you want me to switch it on please let me know.

P.S. geofinder.eu with unofficial FreeCAD phabricator is down, I'm aware of it - it's work in progress.

Yup going to take on the commercial packages very quickly :twisted:

I just got all our code working with the multiple solver changes but will have to do some testing.
We will submit all of this later this week

@sprogan how is the Scipy integration coming along ?
This will be a game changer

@makkemal, I tried to compile your branch but without success (it is not your fault but my compile environment which is a little bit too advanced and needs ickby SMESH patches to work properly). Anyway, are you sure about the tree name https://github.com/makkemal/FreeCAD/tree/rtd_hindlemp as I do not see any specific new constraint code into it :(.
