Introduction of categories

Official announcements

Dear CalculiX users,

We’ve added several new categories to the forum to be able to better group topics and help new users to get started. The following categories are available:

Official Announcements

Official announcements regarding CalculiX releases, important notices, and forum updates. Only admins and moderators can post, but anyone can reply.

Getting Started

Questions from new users about installing (Linux, Windows, macOS), running, and understanding the basics of CalculiX, input files, and simple analyses.

Examples/Tutorials

Example models, step-by-step tutorials, reference cases, practical advice, workarounds, best practices and learning resources for CalculiX.

Model Setup

Defining geometry, meshes, materials, boundary conditions, loads, steps, and preparing input files for analysis.

Analysis Issues

Errors, warnings, convergence problems, performance issues, unexpected results and questions related to the CalculiX solver during execution.

Advanced Features

Nonlinear analyses, contact, dynamics, thermal and coupled problems, user subroutines, and advanced element or material models.

CalculiX GraphiX

Questions and discussions related to CalculiX GraphiX (cgx): geometry creation, meshing, scripting and visualization.

Postprocessing/Visualization

Viewing, extracting, and interpreting results from CalculiX output files (.frd, .dat). Focus on understanding results and troubleshooting output data, not on configuring external tools.

Tool Interfaces

Using CalculiX with external software and workflows: meshing tools, preprocessors/postprocessors (e.g. ParaView, FreeCAD, Gmsh), scripting, automation, HPC, co-simulation, and pipelines.

Code Development

Discussions for contributors and developers working on the CalculiX solver codebase.

Please help us out by re-categorizing your existing topics. We’ll also try to do this manually, but it may take some time.

The categories were chosen based on the existing topics in the forum. We’d like to keep the total number small, but we’ll see how the current concept works out in practice.

Thanks & Regards,

Lukas

Let me know if you need some help. There’s indeed a lot of work, but should be worth it to make the forum more organized.

I think that some questions about issues with user’s cases can fall into multiple categories. Maybe something like this would be better:

  • Official Announcements

……………………………………….

  • Installation and Compilation

  • General Analysis Questions

  • Tips and Tricks

……………………………………….

  • CalculiX GraphiX

  • Third Party Tool Interfaces

……………………………………….

  • Bug Reports

  • Feature Requests

  • Code Development

Thanks for your feedback!

From the description the categories should be fairly unique. But I‘ll practice a little with existing topics and see if this works out or whether there are redundancies or something is missing.
