abq2ccx is a tool to convert abaqus inp file into calculix inp file.
So work is here greatly reduced to run abaqus inp files in calculix.
Calculix 2.22 is here actual state with 141 cards.

abq2ccx is a tool to convert abaqus inp file into calculix inp file.
That looks like a very helpful tool! Has anyone tried it?
Not yet, I just use this approach to adapt the input deck manually. But the abq2ccx tool looks really interesting, especially since it can handle the *PART/*ASSEMBLY structure, meaning that it should be no longer necessary to use flattened input decks and avoid transforming the instances. I’ll definitely give it a try.
I just had a quick look at the source code. Looks promising.
But there seem to be a couple of flaws. (E.g. ROTA for body load is not supported in ccx).
Having reference nodes defined in abaqus in the assembly is also buggy. It seems to overwrite the nodeID of the flattens assembly nodes.
But overall a good starting point!
Best,
Stoli
Feedback at the project with found issues would be nice.
See
Actual state is now at keywords of actual caclculix 2.23 and abaqus 2025.
By finding limitations and errors please inform the developer.
Can you make issues at this project for the developer with some example lines by input, possible and actual result?
Thanks for the useful feedback on the toolbox (and a mention on the slide at wccm), I’m working on a few fixes right now. If you find more issues please let me know!
Stoli: Your issue was solved at abq2ccx 2 month ago.
Do you test again ?
Calculix 2.23 is now supported.
Yes, the assembly node bug was fixed and resolved the main issue with my existing abaqus model database. I am still evaluating a workflow for an automatic conversion of all parts and assemblies (approx. 400 part variants) to ccx.
