skewness

I'm not sure if this is the exact mesh (may have made some changes), but potential foam shows similar results. Here is the checkMesh output. Is there a good description of skewness somewhere? I'm...

I modeled this as a half pipe with symmetryPlane. The outlet has the same phenomenon - U values on the order of 70000 in all directions. This partially rules out my previous theory - that it has to...
