The online version can read arbitrary files, but the issue is the examples shown in the animations were made with the desktop version after I made changes to the file format, so they can't be loaded in the web version. Honestly the web

> Why it is not possible to add the examples? Is there any technical problem or just lack of time? Do you mean a link to open the desktop app? I guess I could try, but I think it's easy enough to find the example manually. There&#x2

1. I wouldn't be able to do that because these examples are only available in the desktop/steam version. 2. Again this is feature is in the desktop version only (check "View charge carriers"). You can reverse the voltage

The electrons are repelled or attracted by the electric field, which is in turn determined by the average charge density. So two electrons in the animation don't directly repel each other, but the electrons do influence each other thro

Not too difficult. Stay tuned for the 3D version.

The simulation does calculations on the fields only, so it keeps track of the average electron and hole density at each point in space. There is, however, a one-to-one correspondence between the behavior of the fields and the motion of indi

Oh, yes. I updated the page so the animations are now under the CC-BY license. Glad to hear you like them!

I recreated Veritasium's setup in my simulator and measured the current through the load resistor, the results of which are here: https://imgur.com/a/sxVihf0 The gap between the wires is about 1 micrometer, so lig

On my info page ( https://brandonli.net/semisim/info ) there's a list of things my simulation can and can't do. After taking a look at the paper you mentioned, I think simulating it may very well be possible, h

That's exactly right! In my simulation quantities like E and J are vectors with x and y components. In contrast B can be thought of as a vector (or bivector, technically) pointing in the z direction, but since it it only has one compon

Brandon here. I was very much inspired by Falstad's applets. I had him take a look at my simulation and he generously offered to make a JS port.
