A region that you select (ESEL) for remeshing can contain the entire deformed domain or a portion of it. A selected region should consist of the same:
Material type
Element type (including the coordinate system and KEYOPT settings)
Thickness (real constant) for plane stress
Nodal coordinate system (except for boundary nodes which can have different nodal coordinate systems).
A selected region should contain all of the highly distorted elements. It is a good practice to select a group of elements slightly larger than the target group of distorted elements so that the new mesh can be assured of a fairly good distribution of nodes on the interface boundary.
If the boundary nodes are distributed too unevenly, the elements attached to the nodes should also be included. The selected region's boundary can have any shape.
A selected region that is too large may require more processing time and more subsequent remeshings. If the selected region is too small to contain all of the highly distorted mesh areas, the new model after rezoning may not be of sufficient quality to achieve convergence.

Using the GUI to Select a Region to Remesh Select a region to remesh using either of the following methods available via the :
This component can be imported into the program or exported to a third-party tool to create a new mesh for the selected region. |
If more than one region requires rezoning, see Remeshing Multiple Regions at the Same Substep.
After you have selected the region(s) to remesh, proceed to Step 4: Perform the Remeshing Operation.
