WebPlease note that you should see at least 2 mesh cells in your layer. Example 2 . Default mesh, Graded mesh. A silver rod of diameter 50nm. In the default mesh, the curved interfaces cannot be well resolved. The graded mesh solution forces a much smaller mesh over the entire rod, introducing many more grid points. WebThey discovered that the FEM converges exponentially when the mesh is refined using a suitable combination of h-refinements (dividing elements into smaller ones) and p-refinements (increasing their polynomial degree). The exponential convergence makes the method a very attractive choice compared to most other FEMs, which only converge with …
