Hello all,

I'm trying to contruct a 2-D flat plate model with 2-D roughness elements in Gambit. I've broken up the model into several smaller bits in order to get a nice smooth mesh. However, I keep getting the following error: "Zero length front edge"???

Does anyone know what this means???

Thanks and Have a Nice Day!!!

may be u have small mesh and then suddnly grow up to big one. so the intermittent cell will have high skewness (high aspect ratio) and limit to zero length. so change the parameters of mesh to have smooth change in volume.

hey, thanks for you response. that helps alot. erika
