Hybrid High Order(HHO) method for Poisson Equation Fencisx demo code

General
1

Hi everyone,

I’m currently learning the Hybrid High-Order (HHO) method and would really appreciate some guidance. I’m looking for demo or example code using FEniCSx that implements HHO in both 2D and 3D (even simple benchmark problems would be very helpful).

If anyone has:

  • Minimal working examples for the Poisson equation and the Heat equation.

  • GitHub repositories or tutorials.

  • Tips on implementing HHO concepts in FEniCSx.

I’d be grateful if you could share them. I’m especially interested in understanding the implementation’s structure and best practices.

Thanks in advance for your help!.

I guess you could consider contacting the author of:

as they implemented similar codes in DOLFINx and state that their code is available upon request.

Thank you so much Sir!.

Respected Sir,

I requested the materials earlier, but I have not received any response yet. Could you please help me regarding this?. At the moment, I need at least a demo code for the Poisson equation using the HHO method, so that I can use it as a reference and modify it for my work. Thank you for your time and supports.
