What is the exact mean of weighting potential?

The class ComponentNeBem3d was used to calculate the weighting field and weighting potential between two plane electrode with 2cm space, the result of the intermediate position between the two plane is:
weighting field=( -0.00000000, 0.00000000 0.49638254)
weighting potential=0.04966208

it seems the weighting potential is less one order of magnitude than normal value.

I guess @hschindl can help.

I’ve forwarded your question to the author of neBEM. He will take a look in the coming days.
