I will change the name. How about adding the real fib deep beam as second reinforced example?
Yes or replace my wall with the FIB wall and add the beam with two spans:

That’s is also a practical one and not just a second wall ;)
very good idea.

femconcrete is in retirement, femconcrete hip, hip, hooray! :mrgreen:

I did a complete rewrite of commit history for https://github.com/berndhahnebach/FreeC ... emconcrete It should be much easier to follow what we have developed harry. Since there where tons of changes it was not easy to assign commits to you and me. Would you give me a short answer it is ok for you in a way it is now. This will be the base for a PR. it is not finished yet but most work is done. :D

The fib example is not yet updated.

Ahh the retirement house is https://github.com/berndhahnebach/FreeC ... mconcrete3

BTW: once this is merged you will be an official FreeCAD developer :D

such stuff is mostly for people not doing anything, but show all other they do the most. At least it was in the country of my childhood. https://en.m.wikipedia.org/wiki/East_Germany but the post and picture are cool anyway :mrgreen:

How about the unit test harry?

I coded the 13 closed form solutions for reinforcement ratio defined here: http://heronjournal.nl/53-4/3.pdf with Python and managed to reproduce the 11 test cases for single stress results (I changed the name for the reinforcement ratio from "Omega" to "Rho" in line with the paper):

Next step the integration in FreeCAD or Paraview
Are the values above the input and output values?

With this information a unit test is very easy do develop. I would go for this if you don't mind.

Are you interested in designing a icon harry? If not I will ask for help in the disign part of the community since I am a very bad in this.

If you are bad then I am terrible. Better ask for support. ;)
