[ANSYS Meshing] Issue with airfoil geometry to meshing

Acostant · January 5, 2016, 15:03

I am trying to desinge a rear wing for my schools FSAE team and I am having trouble with meshing an air foil. In the pictures below the wall is not in the correct location on the meshing module but displays correctly in the geometry module. I believe that this is also causing problems with convergence as the other set of airfoils I modeled for the front wing did not have this issue and the solution converged. thank you for the help.

I think in the geometry module you are displacing a continuous edge and in the meshing you have just selected a part of this edge and named it instead. you can selected all edges and name them as a singular wall by holding control

I have already selected the entire body and named it. It will not let me select the proper wall on the meshing.

DId you make the geometry in design modeler? If not,use the geometry correction options, get rid of hard edges etc

I imported the cat using SolidWorks into the design manager Ivan have a boolean created using a wall for a two dimensional analysis. This issue a curse typically with the bottom or middle wing. This doesn't always happen but occurs 90% of the time.

I've had the same problem in ANSYS 16, but it worked for me in 15 fine. If you can, try that.
