[GAMBIT] Multi-Element Aerofoil Mesh

andyjo22 · March 26, 2012, 18:57

Hi,

I'm new to CFD and currently using Gambit to mesh a double element wing.

Could anyone offer any advice on how to go about it as the methods I have tried so far have lead to solutions that won't converge to 1e-04?

So far I have attempted a C-grid with boundary layers around each aerofoil with a tri-pave mesh.

Many Thanks in advance

Turns out I had too mny elements in my boundary which skewed the cells beyond a satisfactory limit to around 0.98 skew.

Guess I've learnt that rule no.1 of CFD is perserverence

0.98 is to high.
Fix your skewness problem, before solving
