hi all...

I a little bit problem in meshing by using GAMBIT software...

My project is need to determine laminar flow in rectangular minichannel ( 1mm x 1mm )...

after done drawing 1mm x 1mm square, then face it, then i try mesh face and choose interval count = 100, so as the result i get as this

why it show curve at 4 corners? why this happen? how can i fix it? or it is normal so small size?

then i try meshing with same shape but this time is 1m x 1m, an as a result, i get this

Thats a problem with internal tolerances in gambit. As its dimensionless you may scale it up later. Or try Quad Pave instead of Quad Map.

I think Tannemm got the right answer. You could mesh a 1m*1m region and scale it in FLUENT to get a 1mm*1mm modeling or something like this.
