Hello,

I am working on a project with a few wedges. I am making a simple 2D model. Attached is a picture of what I am creating. I create the blockMesh and it works, but with an interesting line:
Quote:
patch 5 (start: 2080 size: 1) name: frontAndBack
which I think is bad because you cant divide 1 by another integer. I think this is the reason why when I use checkMesh I get:
Quote:
***Zero or negative face area detected. Minimum area: 0
and
Quote:
*** Max skewness = 2.33928e+148, 1 highly skew faces detected which may impair the quality of the results
When I check in paraFoam (using the glyph method to show where the zero or negative face area is located) I realize it is at position 15 and 69, which is part of wedge number 4.

I tried changing the wedge from hex (15 15 21 20 69 69 21 20) to hex (20 15 21 20 47 69 75 74) and also changing the empty from (15 69 69 15) to (20 74 74 20) but that didn't work either and it still gave the same error in the checkMesh.

Any help or suggestions on what to do would be greatly appreciated!!!

Thank you,
~Michu
