Darren @1318980,
I have been working hard trying to get the best mesh to start with before I layer the wing.
I have started a new public project with what I have done so far.
There is one geometry and two meshes in the project so far but I am working on the project and may try a simulation soon.
Mesh 1 is just a refined geometry with 2.03 million faces.
Here is Mesh 1 near the wingtip (~12 in chord and 0.17 in TE thickness) :
The 3.02 million face Mesh 2 is my attempt at layering Mesh 1 with the following procedure.
I am using the ~12 in tip chord and 135mph in the yPlus calculator like this:
Then in a spreadsheet I have this:
Then in Mesh Refinement Parameters for Inflation I did this:
Then I started clipping Mesh 2 to view the layers I added to Mesh 1. I am not sure if they are good enough and don’t know where to start to make them better. I do not see an ‘allowable volume ratio’ in the Parametric parameters and I am a little confused about your other suggestions.
Here are the mesh clips, first, right at the wingtip:
6 inches in from tip:
At 1/2 span:
And at the root:
Can you give me any specific pointers to refine the layers now so I can go on and make a 1s simulation to see if I got the average surface yPlus anywhere near the 160 that I want?
Thanks,
Dale
