Guidance required for making a C grid in pointwise

junkie71189 · June 15, 2012, 03:02

Hey guys,

I'm new to using Pointwise and I was wondering if there was a simple way of making a C-grid for a flow over an airfoil case?
In gridgen, I remember that we could choose the same connector twice to extrude in different directions that made life easier. However, I'm not able to find any easy way out in Pointwise. (I also couldn't convert the 2D gridgen mesh to 3D in pointwise)

Also, I had great difficulty in making a grid when the trailing edge was not sharp. How do we tackle that situation?

I tried making one on my own by some regular geometry methods but after using the output polymesh files, the case didn't work.
Help would be very much appreciated!

Thank you in advance
Venkat

Hi Venkat,

Did you figure out how to do your C-grid in Pointwise?
If so, can you post your findings.

Best regards.

Hey,

Unfortunately the C-grid didn't work out quite so well even though it looked good. I ended up using a blockMeshDict file for my findings. This was better but not quite accurate enough specially for drag at lower angles and don't predict stall well enough.
