I have a simple questions on terminology. Is there a difference between softening length and smoothing length? I have been using the 2 terms interchangeably as the minimum distance between particles for calculating particle interactions, and have not found any direct comparison of the 2 terms.
For context, I use computational/numerical physics simulations (specifically the GIZMO code) to simulate gaseous disks around galactic centers, where "particles" represent some mass of hydrogen. Perhaps it's also important to state that I am specifically looking at gravitational interactions at this point. I just want to make sure I am not missing something important.

Thank you

    $\begingroup$ What area is this terminology of? You are assuming that we're all experts in the precise area you are looking at :-) $\endgroup$ Commented Nov 7, 2023 at 22:43

    $\begingroup$ Apologies. I use simulations (specifically the GIZMO code) to simulate gaseous disks around galactic centers, where the particles represent some mass of hydrogen. So the area is in terms of computational/numerical physics, applying to the interactions between hydrogen particles. Perhaps it's also important to state that I am specifically looking at gravitational interactions at this point. Hope this clarifies things @WolfgangBangerth :) $\endgroup$
