Inquiry about the Development Status of CALFEM

[kulasegaram]

Hello everyone! I'd like to express my gratitude to the development team behind the CALFEM project. I have successfully utilized your library as an optional dependency in the project IfcTruss for conducting structural analysis on a truss system.

Now, I'd like to ask for some information about the development status of CALFEM. I've noticed that CALFEM is currently listed as “Beta” on PyPI. I wondered if there's any estimated timeline or roadmap for achieving “stable” status.

Your insights and experiences are greatly appreciated!

Hi!

The Beta-designation have been there since the start of the project. It is probably related to it being a research software project and support is on a best effort basis. On the other hand we try to avoid any breaking changes to the the core modules. Adding additional commands instead of changing the API. The API have been pretty stable during the last 5 years.

I will probably remove the designation from the next release.

Thanks for the prompt answer! IfcTruss relies on the core module and its functions from CALFEM in its _calfem module:

• import calfem.core as cfc
• cfc.bar3e()
• cfc.assem()
• cfc.solveq()
• cfc.extractEldisp()
• cfc.bar3s()

May I kindly inquire if these can be deemed stable and if there are no potential future modifications?

[jonaslindemann]

These routines are considered stable. However, we reserve the right to add features and bug fixes` to these functions. In doing so we will make sure that the old API is still available. cfc.extractEldisp(...) is the old name for the function. I would recommend using cfc.extract_eldisp(...) instead.

Thanks for bringing that to my attention! I will change this in the next release.

I found this function in an example in the documentation:
