Mesh
Now make the settings for the mesh. A finer mesh is necessary to properly resolve the electrodeposition process at the boundary. In addition, we need to change mesh settings to properly remesh the channel as it gets thinner and thinner during deposition.
1
In the Model Builder right-click Mesh 1 and choose Edit Physics-Induced Sequence .
2
Click the Size node and in the Settings window click the Custom button.
3
Click the Size node, and enter the following under the Element Size Parameters section:
-
Maximum element size text field, enter 5e-7. By choosing a small maximum element size, we ensure a resolution of at least 0.5 µm.
-
Curvature factor text field enter 1. The curvature factor is the ratio between the element size and the radius of curvature of a boundary in the model. In other words, we here set that the maximum element size on a boundary should be the same as the curvature radius.
-
Resolution of narrow regions text field enter 10. This ensures that approximately 10 layers of elements will always be used in narrow regions.

The mesh should match this figure:
