FeenoX is a cloud-first engineering tool. This idea is thoroughly discussed in the documentation, particularly in the
As such, it is a tool that in principle should be used from a higher-level interface (e.g. a web-based UI such as <www.caeplex.com>) or called from a set of automated scripts following some kind of parametric or optimization workflow.
In any case, if you want to learn how to create your web-based interface or how to implement an optimization workflow on your own, you will need to start running simple cases manually and then increasing the complexity until reaching the solve state-of-the-art capabilities.
Recall by reading again the project’s main README, that FeenoX is—in a certain sense—to desktop FEA programs (like Code_Aster with Salome-Meca or CalculiX with PrePoMax) and libraries (like MoFEM or Sparselizard) what Markdown is to Word and (La)TeX, respectively and deliberately.
Indeed, it is this the main goal of the tutorials, namely to be able to run relatively small problems in FeenoX by creating the appropriate input files and, eventually meshes or other needed data files. This way, by the end of each tutorial you will better understsand how FeenoX works and thus, how to make it work the way you need and/or want. And if not, you always have the freedom to hire someone to explain it to you and even to modify the code to make it work the way you need and/or want since it is free and open source software.
