Perhaps it would be a good idea to request such changes here: Issues · Luecx/FEMaster · GitHub

I did not have time to integrate the exporter. I was prepared to invest a little time first to see if the solver is worth supporting. After some user tests, I will take the next step.
No need for RC version. Just .0,.1,.2. easy to follow.
2 posts were split to a new topic: Point and line smoothing
The RCs are here so I can fix all new bugs before releasing a stable working 2.6.0 version. Then I will add 2.6.1 as a developer version. The developer versions are not really meant for serious work

choosing which another solver to be supported may not easy decision, compatibility can lead to user confusion also. It seems much worthy if PrePoMax have ability to support large FEM solver format instead integrating one or two alternate solvers only. These directions can be similar to another pre/post processor such as CGX, Gmsh, Hypermesh or GiD

is there any plan to add a heterogeneous material like concrete, and reinforced concrete. it will be a great help @Matej
There are ways to model RC structures using the compression-only material model available in CalculiX (currently, not implemented in PrePoMax and thus requires keyword edits): https://www.youtube.com/watch?v=z5IQuXv8A2Q
However, rebar has to be modeled explicitly.
But check this feature in FreeCAD FEM: https://wiki.freecad.org/FEM_MaterialReinforced
And this tutorial involving it: https://wiki.freecad.org/Analysis_of_reinforced_concrete_with_FEM
There’s even a dedicated add-on workbench in FreeCAD for concrete structures: https://forum.freecad.org/viewtopic.php?t=88953

I think that in first order Prepomax should use open source free solver like CCX or similar clones (the most stable) since Guido go retired next year. comercial solver as premium option I think
Guido retires next year, but CalculiX development will be continued by his team and should be even faster.
There are many good open-source FEM solvers. Supporting the ones with a similar syntax to CalculiX (including already supported commercial Abaqus) makes a lot of sense. For completely different solvers, there would be too much work and it might be better to have a look at FreeCAD FEM which also offers a few different solvers (CalculiX, Elmer, Z88, Mystran, in the future hopefully also code_aster). But the problem is that it’s hard to fully support multiple solvers, usually some will be supported only in a small part and that’s the issue with FreeCAD FEM. Btw. FreeCAD also has some add-on workbenches for less common solvers (some even developed by FreeCAD community members).
Hello,
I have made a RCC section in prepomax by referring your Youtube Video and it works fine, only thing is if there are more Rebars like in columns it takes time to model and run so I thought if they update the software to model these bars easily and if the running time is reduced it would be great work, because what i have seen in Midas Civil and Lusas softwares they are not as user friendly as prepomax and this software has very good potential to compete with those software if they are work little on RCC behaviour.

To model more rebars, we would need some improvements on the solver side such as being able to embed 1D elements inside 3D ones - Abaqus can do this:

You can request that on the CalculiX forum: https://calculix.discourse.group/

yes adding 1D elements in a 3d model would really help.
