<lekernel> what program can I use to compute the electric field generated by multiple electrodes with a given geometry and at given potentials?
<mumptai> cst microwave studio?
<mumptai> or is it just "an oddly shaped capacitor at DC"?

<lekernel> just static field
<lekernel> DC
<mumptai> that's way simpler, but right now i'm not a aware of a software for that (that won't also do the complex stuff and comes with that cost)
<mumptai> what are you trying to solve?
<lekernel> quickfield looks pretty good, if only it weren't windows and evaluation-type license
<lekernel> a pretty simple problem in fact :) four electrodes arranged in a square
<lekernel> with two potential differences for X and Y
<mumptai> some years ago i had a 3d frequency domain solver, that should be able to do that
<lekernel> the end purpose is to be able to generate an arbitrary and constant 2D electric field inside the square by varying those two potentials
<lekernel> I want to simulate it to see how much the electrodes for one axis will mess up the others, and what I can do to prevent this (eg space the electrodes etc.)
<mumptai> reduce the poles to infinitesimal small charges and calculate the superposition of the filed of all four at any place you are interested in
<mumptai> and be a bit carefull that the reduction of the pole size stays valid
<lekernel> how can an infinitesimal small charge generate a constant potential (inside the electrode)? this doesn't sound like a good model...
<mumptai> it isn't
<mumptai> its just simple
<lekernel> too simple I think :)
<mumptai> but it hold up as long as you are far away from it
<lekernel> I'm not. the very purpose of this simulation is to see what happens close to the electrodes
<mumptai> if the electrodes are big compared to their distance, it won't work too well
<mumptai> okay, than you need to work with the integrals covering the electrodes surfaces

<lekernel> this is holding the two vertical electrodes at half potential
<lekernel> if I don't... there's a very bad "shielding" effect http://imgur.com/La0Ue

<mumptai> but could let the side plates just float
<azonenberg> lekernel: unrelated question, are you familiar with NoC architectures at all?
<lekernel> mumptai: which requires transformers in the drive electronics ...
<lekernel> azonenberg: a little bit
<azonenberg> lekernel: Would you be interested in commenting on a very early draft of a paper i'm writing?
<azonenberg> Right now i'm basically proposing what i want to make, most of the code isn't actually implemented
<lekernel> just ask... :)
<mumptai> or high-value resistors
<mumptai> (comparable to the resistor ladder in a pmt)
<azonenberg> lekernel: see PM

<larsc> how does a NoC work? Instead of a register read or write you send a packet and at some point get an answer back in another packet?
<lekernel> usually yes
<larsc> interesting
<lekernel> the problem, of course, is that every transfer has massive latency
xiangfu has quit [Ping timeout: 276 seconds]
<larsc> well I suppose that's one of the interesting reasearch topics in that area, how to keep the latency reasonable low
<larsc> reasonably
