Global Element Seed Size? Tetra meshing issues
 

Hi:

I am a new to ICEM. I am very much familiar with Pointwise/GridGen.

I am using Ansys Workbench 13. I have a couple of quries:

1- I am meshing on a cone-cylinder body using tetra meshing, following tutorial of helicopter meshing step by step. Can any1 explain me:

• how to create farfield and symmetry surface and how to intersect body with the symmetry plane?
• I have tried but not succeeded in.
• Explain exactly what global element seed size mean?
