The geometric shape defines the mesh structure, so obtaining mesh structures according to the geometric shapes is a very important thing in Finite Element Analyses(FEA). Also, you can adjust the structure of mesh in ANSYS® Meshing according to your geometric shape. If your geometry has curvature features or curvy entities, you can adjust the Sizing Function of your mesh as ‘Curvature’. In this article of Mechanical Base, we will show;
The default option for Size Function in ANSYS® Meshing is ‘Adaptive’ that the size function will be defined by the system. But if your geometry is very straightforward that has lots of curvatures inside it, you can adjust it to ‘Curvature’ as shıwn by the green arrow above.
So Curvature Size Function provides proper meshing element structures according to the curvature of the entities that the mesh elements will not violate the curvature in this entity. The mesh size parameters are also defined by the user in the ‘Curvature’ option in ANSYS® Meshing. You can adjust these parameters for Curvature Size Function below;
The mesh structures of curvy faces or curvy geometries will be adjusted according to these values that you entered in Curvature Size Function in ANSYS® Meshing.
