Hello,
(This discussion refers to paper in www.comsol.com/paper/3d-simula...ion-in-a-squid-giant-axon-7317)
Perhaps I'm mistaken, but I think that there is an error in the paper.
For me, it would be better to include
Image may be NSFW.
Clik here to view.
, i.e. let it as it comes by default, and
Image may be NSFW.

(this as there's no laplacian term for Image may be NSFW.

).
And I would change F (the source term), to the rest of terms in equations (1) and (2):
Image may be NSFW.

, and
Image may be NSFW.

.
If one does what authors say in equations (4) and (5), all those terms would be affected by the divergence operator (acting on Image may be NSFW.

), and that's not possible (as they are scalars, not vectors, and the result, if possible, would be different from what appears in equations (1) and (2)).

Jesus.
