as I have written in the thread Boolean-like parameters in ccx input keywords, I’m currently working on a python framework, called Pygccx, for building and solving 3D solid CalculiX models.
Now my project has reached a certain level and I would like to make it open source under GPL V3.
I would appreciate if someone wants to take a look or give it a try. Maybe someone would like to contribute? There is still a lot to do:
Implementing new keywords, writing tests, writing more and/or better documentation, refactoring, improving usability and a lot of discussion.
To get a first impression, look at the files in the examples folder.
In the folder doc/pygccx you can find an auto generated html documentation of all classes.
If there are any questions, I will do my best to help.
Hello Ihor,
that would be great! Can you create the repository? At the moment I’m still working on a parser for frd and dat files. When that’s done, maybe in one or two weeks, I’m happy to move the project to the new repo.
Yes, I can create the repo, but it is not needed. Much simpler is to transfer your repo directly to the organization.
By the way, while you’re working on FRD and DAT parsers for CalculiX, please have a look on those projects: ccx2paraview - module reader.py is a FRD parser, CCXStressReader - is a DAT parser for Calculix.
Hi Ihor,
i have transfered my project to Calculix organisation. Thank you!
It seems i have limited access now. Can you please rename the repo from “pygccx_project” in “pygccx”.
Many thanks!
Looks very interesting! I like the idea of making simple 3D meshes with just a few inputs. I seem to be getting the following error when running the beam.py example though:
[hussaif1@delltower48 beam]$ python3.10 beam.py

Hi!
Thank you for your feedback! I was able to reproduce and fix your error.
The problem was, you downloaded the latest development version from the master branch and not from the releases.
The master branch is the latest, but may contain some issues.
The releases are more stable and tested.
or
Please download the latest version from there, install it via pip and try again.
Maybe you have to uninstall your current version of pygccx first.
Thanks. I removed the pygccx/ folder then did another,
git clone https://github.com/calculix/pygccx.git
and it now works! I also was able to add a model.show_gmsh_gui() to the beam.py example and it brought up the gui. I just now need to figure out how to export images of the geometry with the surface numbers on them. Perhaps I will ask on the gmsh forum if you are not sure off-hand.
A good starting point for the Gmsh Python API is here:
To export a figure: model.get_gmsh().write('my_image.png')
if you want to export an image w/o opening the gui, call first model.get_gmsh().fltk.initialize()
Hi. I installed the release version 0.1.0, but it still shows some errors. (Just a preface: I’m new to CalculiX, so I figured the build you made with python would be an easy jump for me to understand the code).
I ran the beam.py example, which seems to have a type error.
Hi!
I have tried to reproduce your error but with no luck.
I have set up a new virtual env (Python 3.10.5), downloaded the release 0.1.0 and installed it with pip. Then i ran beam.py and it worked.
The error says, object ElementSurface has no attribute ‘type’, but when i hook in the debugger at line 84 in beam.py, the attribute is there (variable load_surf).
Can you please give me some information which OS you are using and which python version?
Hi,
i have ran your inp file directly as well as your beam.py. Both with calculix_2.19_4win\ccx_static.exe and it converges fine.
Which ccx version did you use? Maybe its an issue with ccx?
