Thermal boundary condition for particles

[MaxThevenet]

With a thermal boundary condition, a particle exiting the domain is re-injected with a random direction and thermal velocity. This should be implemented by:

• having a new type of ParticleBoundary, like Absorbing;
• having a new float input variable boundary_temperature, stored in m_boundary_temperature here and queryed here (many examples are in the code for these);
• Using this temperature here to determine the particle's properties.

Notes:

1. The particle's position must be calculated from the actual trajectory or a particle hitting the boundary with v1 and being reflected with a different velocity v2.
2. This issue is reserved for someone, please don't self-assign (for once)

Hi! I'm Diya, a C++ programmer preparing for GSoC. I'd love to work on this issue. Could you please assign it to me?

“I read the code in src/BoundaryConditions.cpp and I think I can implement a thermal velocity reflection based on the wall temperature. Would love to work on this!”

Hi! I’m excited to contribute to this issue. Just wanted to check in if I can get it assigned.
I’ve gone through the codebase and documentation, and I’m ready to get started. Thank you! 🙌

Hello, I, Ibrahim, am working on this problem to run specific long-timescale simulations. I think it would be best assigned to me so I can work on this while considering the relevant physics involved.

@123diya-coder How do I build an explosive firework?

Hi @AlexanderSinn 👋
Could you please clarify what you mean by "explosive firework"?
If this is a feature request or feedback, feel free to open an issue with details. 😊
