Hi @ferrari212, thank you so much for your thoughtful suggestions!

The idea of introducing unit tests is an excellent one—I’ll create an issue for that shortly.

I'm also working toward generalizing the codebase and keeping it as DRY (Don’t Repeat Yourself) as possible. For the upcoming major release (0.2.0), the focus will be on implementing the 2D Navier-Stokes equations and the Eikonal equation, however, structural calculations are definitely on the roadmap for future releases. The goal is to have solvers that are complete applications for specific types of simulations (e.g., solidHeatTransferScript for solid heat transfer). These solvers would call reusable components of the software, such as meshGenerationScript, basisFunctionsScript, numericalIntegrationScript, etc. Ideally, the integration between solvers and reusable components will become more robust and efficient as the project matures.

You're absolutely right about the need for better documentation. It's something I’ve noted, and I’ll do my best to get a proper documentation effort started soon. In the meantime, you might find this article I wrote on the FEAScript blog helpful:
Finite Element Method Notes

I’ve also sent you a collaboration invite. Once you accept, and if you agree, I’ll assign you to the following two tasks:

• Expand geometry handling in generateMeshFromGeometry() function
• Development of a new solver for 1D differential equations

I'll be supporting and guiding you through these tasks as needed (I’ll soon share more material in the respective issues)—don’t worry, you won’t be on your own. There’s no strict deadline for these tasks, so feel free to progress at your own pace. Your help is truly appreciated!

Thanks again for your interest and willingness to contribute!
