Subtracting 3D Bodies From Themselves In Siemens NX(Illustrated Expression)
In ANSYS meshing, there are bunch of mesh optimization tools and you need to optimize your mesh structur according to your physical model in ANSYS. One of these mesh optimization tools is ‘Span Angle Center’ option. In this article we will explain;
To adjust the Span Angle Center, click on ‘Mesh’ tab as shown by red arrow above then click on little pop up menu at Span Angle Center section as shown by red box above, then select a option such as, Coarse, Medium and Fine.
Span Angle Center option is the curvature mesh refinement. Mesh structure divided into curved regions until individual mesh elements span this curvature angle. You can choose one out of three choices as;
Coarse: 91-60 degrees of angle will be spanned.
Medium: 75-24 degrees of angle will be spanned.
Fine: 36-12 degrees of angle will be spanned in the mesh structure.
The mesh will be finer in curvature regions if you select lower angle valus for Span Angle Center option in ANSYS Meshing.
The general case of Span Angle Center option in ANSYS Meshing is like that.
