Refining a mesh using field data

Use the Refine Mesh from Field command to apply the size information from a mesh size field to an existing mesh. The software iteratively refines the existing mesh until the element sizes match those in the mesh size field. This iterative refinement is similar to the iterative remeshing that occurs during an adaptive solution process. However, the Refine Mesh from Field command does not perform a solve.

The Refine Mesh from Field command is helpful if you want to use the results from an adaptive solution process to refine a mesh on a slightly different part.

Existing tetrahedral mesh.	Mesh modified with the Refine Mesh from Field command. The mesh converged after three iterations using a mesh size field created from an adaptive solution process on a similar part.

Controlling the refinement process

You can use the options in the Refine Mesh from Field dialog box to control the remeshing process. For example, you can specify:

• The maximum number of iterations.

• A target minimum element length.

• The maximum amount of element refinement allowed in each iteration.

The software considers the remeshing process to be converged when the sizes of the elements in the mesh on the part match the element lengths specified in the spatial field..

Viewing iteration details

For each iteration, the Information window lists information about the status of the mesh, including:

• The total number of elements and nodes.

• The current residual mean square error value.

• The convergence status of the mesh.
