Feat/charge patterns #27

Open yzuuang opened 3 years ago

yzuuang commented 3 years ago

Electrostatic with potential, gradient and curvature.

sannant commented 3 years ago

You implemented the net force and it's potential and derivative.

I think you at least also have the stress distribution at least in overleaf. Can you also implement this ?

I think we discussed that the derivative and potential to the stress field according to the gap field is more tricky.

implements #26

Do you mean the stress distribution in space? i.e. change of stress according to the space distance z rather than gap distance d?

sannant commented 3 years ago

I mean pressure as a function of x and y

yzuuang commented 3 years ago

of x and y

OK I got it. But actually in general cases, a function of x and y is not really possible. Or should I just integral back from Fourier space to compute E-field? Then it will be a variation to the original Persson's method.

sannant commented 3 years ago

I guess you can only compute sigma(x, y) from the realspace electric field yes.

@sitangshugk95 I merged master in the code and the tests pass without bug. However, some tests need to be improved to add checks of the accuracy of the results. I opened an issue for that.

@sannant - what do we do with this?

sannant commented 1 year ago

I would keep it like that until someone eventually follows up on the work (which might be forever ).

But I am happy to help out (we have quite detailed latex notes on the derivation of the formulas) if someday someone takes over.

Okay sounds good
