This discussion forum is the place for conversations, questions, etc. that are not related to code. For bug reports and feature requests, open an issue instead.

Even if informal discussions are welcome, please follow these guidelines when opening a new discussion (similar to those for issues):

• Be clear, concise and complete in your message. Include illustrations if they help to describe the problem.
• If appropriate, provide all necessary input for FEPX (i.e., configuration and mesh file, as well as any other optional input files) or, alternatively, the Neper version and commands used to generate the input files. Additionally, include the complete terminal output. If possible, always provide a minimal working example that can be used to illustrate your problem, that is, complete but excluding unnecessary options, large inputs and excessive computation times. The example should include the program commands and terminal output as plain text (no screenshot, etc.), and be provided between triple backticks (Markdown formatting, see https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks), as shown below:
