Re: [Eidors Help] Complete circular electrode model in 2D

[Bartek G. <b.g...@gm...>]

Hi there,

To get help, please post code rather than data, or at least code that uses
data, which in your case is code that loads the mesh from gmsh and makes an
eidors image struct out of it. Clearly, that's where you're making a
mistake.
