I'm attempting to create a set of 2 square ducts connected by a small gap, and have been following the tutorials word for word, however I still get an 'ill defined primitive entry' error and I cannot for the life of me figure out why:

"ill defined primitiveEntry starting at keyword 'boundary' on line 101 and ending at line 166"

It's also interesting top note that the file only has 164 lines, not 168.

Can anyone spot the issue?

Hi,

The last line in fixedWalls. Comment is a little bit messed up.

Yet after you fix comment, you will encounter

face 0 in patch 2 does not have neighbour cell face: 4(0 1 24 25)

Which is up to you to fix.

[saddy]

your error is:
1.stop using curly braces in your patches section for gods sake
that will resolve the error

if not reply with additional errors
i am happy to shoot down errors. i know solution to all blockmesh errors
