Checking aspect ratio in Gridgen software

madhukar_nal · April 8, 2010, 06:25

Hi,
I created 2D structured grids on symmetric airfoil. Now i need to check aspect ratio of the grids near the airfoil surface.Even i checked in examine the grids details.
can anybody tell how to check aspect ratio near (particularly) the airfoil wall surface.

In Gridgen:

- Domains (D) > Examine (e)
- choose your 2D airfoil domain
- Function (f) > Aspect Ratio (a), Done (ent)

If you want to change the min/max on the color bar go to

- Display (t) > Color Bar Values

Hi chris..
Thanks for reply..Actually i need to find out aspect ratio near the Airfoil wall only..I already did that method (Examine option)..
is there any method in gridgen to find out aspect ratio in terms of numerics (apart from color bar)...?

So you would like to know the numerical values of the aspect ratio of the cells along the airfoil surface?

My suggestion would be to use the scripting language, Glyph, but it's not possible in Gridgen's version of Glyph.

What you are looking for is possible in our new meshing software, Pointwise. Both graphically and through the scripting language.
