Hello Bill,
I apologize. I sent the wrong script previously. The above corresponds to the
grid I created. I do not use "prevent hole cutting," and it appears to properly
interpolate. However, my issue is that in the middle of the a column of zero
appears to be the solution where the grids interpolate, rather than the linear
gradient that occurs at either side of the boundary. Based on my intuition, I
do not think this should be the case. Is there a way to combat this issue?
Bestm

hi Ohi,
The script you sent does not seem to correspond to the grid in the figure.
Where the grids join in the middle they should be interpolating from one
another (bc=0).
You should not need to use "prevent hole cutting"

Hello Bill,
I wanted to follow up on the grid that you sent me. To make it more like the
domain I want, I removed the inlet and added two more main channels and
corners. I did not have to use hole cutting here, but there appears to be an
issue when I solve the Laplace equation within this domain. At the points where
the left and right sets of grid are interpolated, there appears to be a
discontinuity in the solution. I have attached the Ogen file, a picture of my
mesh grid, and a picture of the solution. I have played a lot with the number
of lines in my grid and their overlap length, but it appears to have no effect.
I wanted to know if you have any tips for me as to how I could fix/debug this
issue?
Thank you for your time,
Ohi
