Wave equation

[zmaril]

Hello! Really cool library you have here! I was wondering, would this support solving the wave equation with arbitrary polygon boundaries? I have a project that requires me to solve those sorts of problems and visualize them. Thanks!

Hi Zack,

Thank you for your interest in the project and for reaching out! Unfortunately, FEAScript doesn't currently support time-dependent equations like the wave equation.
Regarding arbitrary polygon boundaries, I'm actively working on a .msh import tool (#5) that will allow importing meshes generated with tools like Gmsh (https://gmsh.info/). Once completed, this feature could potentially be used in such applications.
I’m sorry FEAScript doesn’t meet your project’s requirements at the moment. However, extending support for additional solvers, including time-dependent ones like the wave equation, is definitely on my roadmap. If you’re interested, I’d be thrilled to have you contribute to the development of this feature!

Best regards,
Nikos

Is the .msh import has been completed or still on the go? Your library seems interesting and i would like to contribute

Unfortunately it hasn't been started yet, due to limited time. You are more than welcome to contribute! Check the corresponding task here #5

Yup will do that.

The .msh import tool has been moved to a separate issue: #5

[nikoscham]

This issue has been added to the FEAScript roadmap for the upcoming 0.2.0 release (https://github.com/orgs/FEAScript/discussions/17). Specifically, it relates to implementing a new solver for the Eikonal equation, aimed at modeling propagating wavefronts.

Tasks

• Create a new frontPropagationScript solver following the modified Eikonal format presented here
• Integrate with the Newton-Raphson nonlinear solver (#22)
• Create a new tutorial

The development of this feature is performed on the feature/frontPropagationScript branch

[nikoscham]

The frontPropagationScript solver has been implemented (see https://feascript.com/tutorials/solidification-front-2d.html). Further optimization is still required. Thanks @zmaril for the initial idea.
