Curve Mesh
Introduction
To create a bar2 / bar3 mesh, the input should be a bar body.
Mesh Size
Average element size
The Average Element Size is the distance between two end nodes for Bar mesh.
Minimum element size
The Minimum Element Size is used to remove all the elements that have element edges less than this value.
Grade factor
The mesh size transition on a Bar mesh is controlled by Grade Factor. Default Grade Factor value is 1.5. (Average Element Size marches 1.5 times from fine to coarse).
Geometry Approximation
In case of curved edges, the curvature is captured based on Maximum angle per element and Curvature minimum element size along the curvature direction. By varying the Maximum angle per element and Curvature minimum element size, the desired geometry approximation can be attained.
