 jartok | Ideally, it would be nice if we can use this program, because core part (The TLI has three parts: reduction- null point exists inside a cube or not?, analysis- further exploration and pinpointing to sub-grid accuracy) has been already done- may be someone can add some modularity to it to make it applicable for multi-spacecraft data as well. | 18:51:31 |
| jartok | Does anyone know how I might get in touch with the developers? Kind of feature request... | 18:54:10 |
| jartok | That's for the next time- Need to go now.
Thanks for the exchanges, folks. | 18:54:37 |

Does anyone know how I might get in touch with the developers? Kind of feature request... Yeah, raise an issue on GitHub for feature request.

| jartok | Hi again,
I think I am a little clear about my understanding on my own question. "I think", not too sure about it, but the necessary procedures may be already in place?
Let me explain.
My earlier question:
My question is how do I interpret this "[-0.5, -0.5], [0.5, 0.5]",
I mean, in my case I only have one single float value for Bx1 (eg.1.3665584), and another float value for Bx2.. etc.
They are just location coordinates like, [x1, x2] and [y1, y2].
I my case, I will have 4 of them in 3D, (x,y,z) from each MMS spacecraft (mms1, mm2, mm3, mms4)
i.e. [x1, x2, x3, x4], [y1, y2,y3, y4] and [z1, z2, z3, Z4]

My understanding is that all four MMS SC are used to locate null points in the magnetosphere.
Then, how do I pass 4 different datasets to this function?
I will probably have to transform the 4 data points (Bx, By, Bz from each spacecraft) into 8 vertices of the cube that Haynes's TLI needs to interpolate. Can someone please confirm?
| 03:49:40 |
| jartok | But reading 3 sets of data from the data files will not probably work... we need some kind of field reconstruction, and then transform the 4 data sets to the 8 vertices. | 03:52:20 |

My understanding is that
"u_arr": np.array([[[-0.5, -0.5], [0.5, 0.5]], [[-0.5, -0.5], [0.5, 0.5]]]),
in https://docs.plasmapy.org/en/stable/notebooks/analysis/nullpoint.html -- 2nd half (arbitrary regular grid) ... these [-0.5, -0.5] are magnetic fields (eg: Bx, By) at the vertices of the cube.
Again, can someone please confirm?

Any idea? | 03:56:15 |

Hi, all. I have a question about whether PlasmaPy can be used in Hall thruster wall erosion simulation or thruster plasma dynamic simulations. Did anyone try something like this? | 18:24:24 |

Has anyone simulated a vacuum arc? There are few mechanisms that can generate vacuum arcs. Which step would you like to simulate? | 08:49:21 |

I like to see how the plasma plume expand, and quantify how much of a metallic plasma will stick on a surface. it's a complicated problem. I guess PIC codes are of use in such case, isn't it? | 21:05:23 |
