The Finite Element Method in 1-D
The mesh density is increased where the error is largest. Hence, the final (and computationally most expensive) solution will have a mesh that yields the
greatest accuracy with the fewest possible mesh cells.

Adaptive Mesh Refinement
View of initial mesh
The projection of the 3-dimensional mesh onto the plate surface creates a triangular mesh. The initial mesh is as coarse as possible while still representing all geometric features.
