Wrong coordinates in tutorial notebook about gimli HOT 4 CLOSED

You are referring to https://www.pygimli.org/_examples_auto/3_ert/plot_modTank3d.html

The model goes from x=0...0.99, y=0...0.5 and z=-1...0 after:
plc = mt.createCube(size=[0.99, 0.5, 1.0], pos=[0.495, 0.25], boundaryMarker=1)

The reference (current) electrode (-999) is
plc.createNode([0.5, 0.5, -0.5], marker=-999)
at the side opposite to the electrode line.

The calibration node
plc.createNode([0.75, 0.25, 0.5], marker=-1000)
is inside.

The refinement electrodes obtains z=-0.501 but this is inside. Am I wrong?

from gimli.

The box extends from Z=[-0.5 to +0.5].
I think this is because when you set the box,

plc = mt.createCube(size=[0.99, 0.5, 1.0], pos=[0.495, 0.25], boundaryMarker=1)

You pass the arguments as pos[x.y] and not pos[x,y,z]

from gimli.

Yes, you're right. The pos vector should have a ,0 for clarity and the refinement node for the reference is outside. I guess this will mainly affect the accuracy in the vicinity of the reference. Can you check what happens if you move the node up and not down or the reference line to z=0?

The forward solution changes slightly solution will slight change (I suppose it's more accurate).
