I wish to create a sizing function in ICEM meshing, contained in ANSYS 12.1. I would like to have the source be a surface, and I can only figure out how to set the source to be a point, line, or triangle. I know you can generate this type of sizing function in Gambit, but I have been unable to do it in ICEM. Any assistance you can provide would be appreciated.

In ICEM CFD you set the size on the surface. You can also set the "width" on the surface, which will be the minimum number of layers of elements off the surface before the mesh transitions into the volume. You can also set the Tetra size ratio which will be the overall average growth ratio after the width...
Many users don't set either the Width or the Tetra ratio, but just turn on the sizing function globally.
Go to the Mesh Tab => Global Mesh Setup => Global Mesh size... Scroll to the bottom of the DEZ and "enable" the "Curvature/Proximity based refinement" section.
You can get the details of what does what from the Help (click the question mark in the top right of the DEZ)... but basically, this applies globally when you are using the Octree Tetra method. It will work with other sizes you have set on surfaces, curves, etc. And the smallest size always wins.

Any change in size functions in R 14.5?
