Very large resistivity needed to mimic an insulator

Open schmitts opened this issue 3 years ago • 4 comments

A (very?) large resistivity is needed to mimic an insulator. Not sure if really a bug. Comparison with some other simulator or solving the math by hand needed. arbor_insulator.py.gz arbor_insulator

Hi @schmitts,

do you have an idea whether this is a bug, a missing feature, and how others in the field handle this? Where would an insulator need to be modelled?

@thorstenhater a comparison with some other simulator would be necessary. I'll try to put it together.

Hi @schmitts,

any news here? Just a thought: Wouldn't an insulator imply your are actually looking at two cells? Or at least a different morphology, where the insulating segment is simply removed. For the latter, we recently added some editing capabilities.

To debug these sorts of things, it would be really good to be able to query the total quantitites (capacity, axial resistance) per and between segments. We've discussed this with @halfflat in the chat, cf. https://gitter.im/arbor-sim/community?at=62907770da83520ac34f5e89.

As discussed, insulators are either huge resistivities or simply non-existent in the morphology.
