poimesh
(Not recommended) Generate regular mesh on rectangular geometry
poimesh
is not recommended. To solve Poisson's equations, use
solvepde
. For details, see Solve Problems Using PDEModel Objects.
Description
[
constructs a regular mesh on the rectangular geometry by dividing the rectangle into
p
,e
,t
] = poimesh(g
,nx
,ny
)nx
pieces along the x-direction and
ny
pieces along the y-direction, thus resulting in
(nx + 1)*(ny + 1)
nodes in the domain. The
x-direction is the direction along the edge that makes the smallest angle
with the x-axis.
For best performance with poisolv
, the larger of
nx
and ny
must be a power of 2.
If g
is not a rectangle, poimesh
returns
p
as zero.
