Local mesh refinement
Tools are provided to create graded meshes, so that areas of interest can have smaller and more numerous elements.
Line, quadrilateral & hexahedron elements can be sub-divided along the element edges to create smaller elements.
Change to higher order elements
Linear line, quadrilateral & hexahedron elements can be sub-divided along the element edges to create quadratic elements.
A toolbar button can simply refine the entire mesh, or selected sections by a linear factor of 2.
2D templates patterns can be used for refining quadrilateral elements.
Likewise, 3D templates are available for refining hexahedron elements.
