I'm fairly new to Pointwise and still learning how to use it. I'm currently trying to create an unstructured surface mesh for a wing in which the CAD was not created by me. My question is about the projection of the connectors onto the curved surface on trailing edge of this wing. I've tried creating an abundant of connectors/points onto it and tried spacing it evenly hoping for the connectors to conform more to the curvature of the database. I'm not sure if it will be a problem if I continue to generate the mesh and place it the solver that I'll be using, which is FUN3D. I only think it will be a problem just from looking at the projection of the connectors to the database surface being off. I've attached the images below hoping it showcases the issue I'm facing. In the images, green/teal colored lines represent the connectors and the off white lines represent the database.

Thank you!

Hello! The type of projection may be wrong. Try using linear projection

This is probably just a rendering issue.

The long curve is drawn by OpenGL as a series of straight line segments. The default settings in Pointwise are probably not working on this long curve.

The grid points are actually on the "true" curve. They do not match visually with the curve because there are many more grid points than there are OpenGL render points. Increasing the display resolution will make the grid and curve match more closely.

You can change the render resolution:

• Select the curves/surfaces you want to adjust
• Menu View, Attributes...
• Open the Advanced section
• Increase Triangle Density (range 1-256) to make surfaces "smoother"
• Increase Line Density (range 1-256) to make curves "smoother".
• Press Update Entity Display

I have attached an image showing a highly exaggerated representation of what I am describing and a zipped PW file that shows this concept using connectors on a curve.

Thank you so much dgarlisch! Your explanation on my issue makes perfect sense and it worked without a hitch when I applied it!

Appreciate the help Kirill-MIPT! I might try that for a different case.
