XC, opensource structural engineering FEM code

[bernd]

do you think it is valuable for working on it Seriously?

From what I have seen so far. Surely yes!

Even with license issues of OpenSees?

AFAIK this is not a problem at all. We even could use a closed source solver. We do not use the solver as a library. Means we do not integrat one line of solver code. We just run the binary of the solver. Means AFAIK it does not matters which licence the solver has.

surely. we can tell the user that legaly preparates that solver and this is up to the user of software, but for opensees it's not problem. we can develop own pre and post processor for example in GPL lincence.

FreeCAD use LGPL whisch is not compatible with GPL...

I wanted to install xc on ubuntu 18. I followed the instruction for install on ubuntu.

1- first i install dependency. this is export of command:

Code: Select all

it seems it installed all required packages.

2- then i entered this command for installation of xc_basic:

Code: Select all

ebi@lenovo:~/xcfem$  bash xc_code_install.sh
CMake Error: The source directory "/home/ebi/xcfem/build_xc/xc_basic/src" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.
make: *** No targets specified and no makefile found.  Stop.
ebi@lenovo:~/xcfem$

i think it's related to xc_basic that developers decide to merge it on xc.

thanks a lot

This one ? https://github.com/xcfem/xc/blob/master ... l.linux.md

it seams Numpy is missing, which is needed to build Mayavi

thanks. I used your script for installation. it remove xc_basic that seems have been merged into xc repository.
I run that script line by line and had been arrived to this line:

Code: Select all

cd build-xc_utils
cmake ../xc_utils/src

and export:

my default python path is:

$ which python

I think problem is that xc uses python2, although my default python is python2:

Code: Select all

and for this command:

I don't know how can tell the xc that use python2. Thanks.

[bernd]

it seams you have not installed all required packages ... Try this commands ... https://github.com/xcfem/xc/blob/master ... _bionic.sh before you gone start with xc_utils

[ebrahim raeyat]

Thanks @bernd. finally i installed xc on ubuntu. I want to know:
1- Is there any GUI in progress for xc?
2- Is it better for start, to explore examples or may be a better way?
3- Is xc installable on windows machine? no at present, but possible for future?

thanks a lot.

[bernd]

no GUI at all. Any input is done in Python. This is what we could use FreeCAD for.

try the unit tests ... https://github.com/xcfem/xc/blob/master ... sh#L64-L69 or try the examples of ana ... https://github.com/anaiortega/XCmodels or very simple ones here https://github.com/xcfem/xc_examples

I am ready for 3-4 years or more work on this project! but one question:
is there any roadmap for Gui? is there any sample from another software in your mind?
i think ETABS is a good sample for this work.
