Hi Ana,

just some basic question. Is XC a fork of opensees or is it based on opensees and the opensees code in XC will be updated from time to time when opensees will be released in a new version?

cheers bernd

Hi Bernd.

It's not a fork. It's based on Opensees code and we import new Opensees features as they become available. From time to time I ask mysekf if it is the right way but, when I started to write XC back in 2004, I didn't even know what a fork is.

Cheers Luis.

There are also features, like linear buckling analysis or modal analysis, that are not available in Opensees (as far as I know).

2004, wow what a long history XC has ...

Have you ever pushed back some of the changes to Opensees upstream?

Hi.

No. As far as I know Openers is developed by a mostly academic community. I imagine that it is not impossible to become a member, but it seems not very easy....

I didn't found neither an easy way to make contributions to the source code.

Cheers Luis.

On FreeCAD we are very happy about any value contribution. But FreeCAD is a real community project. Might be opensees is different, but you never know ... it also depends how difficault it is to make a PR. On FreeCAD and XC it is very very easy.

anyway thanks for the informations Luis.

cheers bernd

I recently made a commit on Opensees, they accepted it. It's not anything technical but nevertheless, they accepted it.

It seems it's somebody which has uploaded the Opensees sources, not the Berkeley University itself.

The OpenSees github repo is managed by Frank McKenna @fmckenna from UC Berkeley. It is "official".
