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
![]()
, i.e. let it as it comes by default, and
![]()
(this as there's no laplacian term for ![]()
).
And I would change F (the source term), to the rest of terms in equations (1) and (2):
![]()
, and
![]()
.
If one does what authors say in equations (4) and (5), all those terms would be affected by the divergence operator (acting on![]()
), 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)).
Regards,
Jesus.
