 June 1, 2010, 04:50 Question about creating the geometry in ICEMCFD #1 New Member   cxcxcx0505 Join Date: May 2010 Posts: 17 Rep Power: 8 I am meshing 2D airfoil in ICEMCFD. I saw a tutorial in youtube,but it used "formatted point data" to input the geometry.The ratio of the far field boundary to the chord length of my project is much more bigger.I need many points in order to create a nice mesh.So,I plan to import the geometry using other method like DWG or something else.Is there any other method to build the geometry because I am quite blur how to input the function of y to create the geometry without using points or using points. Thanks.

Or perhaps he wants you to have more mesh points. Because the curve is "curved" thru the points, you get good resolution with that number of points, even if you wanted 500 mesh points along the leading edge. Simon

actually I got another question to ask,when I first import the geometry from "formatted point data",the "Curves" do not appear at the left column of geometry as like the video tutorial at youtube ,only have "subsets" and "point",my version is 12.1.I face problem when I want to associate the edge with curve
