PROBLEM
- 3D Rectangular Plat, k31 Mode, PZT4 = 40mm x 6mm x 1mm

MESHING 
Free Mesh
Meshing -> Generate -> Enter size of elements (4) -> Mesh Generated ->
Number of nodes should not exceed 500 for ATILA Light
Version
Mapped Mesh
Meshing -> Structured -> Volumes -> Select all volumes -> Then Cancel the
further process
Meshing -> Structured -> Lines -> Enter number to divide line -> 8 & 4
are assigned to x and y axes
In practice for ATILA Light Version, choose 1 to z axis,
1 or 2 to y axis and 4 or 8 to x axis. 8 is required to show the second resonance
vibration for obtaining the better position resolution.
