II. How To Use ATILA

3.3 Multilayer (2)
BOUNDARY CONDITIONS MESHING


PROBLEM - 3D Two-Layer, PZT4, 10 mm x 5 mm x layer thickness 1 mm, Interdigital Electrode


BOUNDARY CONDITIONS
Potential

Data -> Conditions -> Surfaces -> Potential 0.0 (or Ground in ATILA 5.2.4 or higher version) -> Assign the top and bottom surfaces -> Forced Potential 1.0 -> Assign the center surface

Polarization/Local Axes

Data -> Conditions -> Volumes -> Geometry -> Polarization (Cartesian) -> Define Polarization (P1) (0,0,1) direction

Choose X and Angle -> Define X axis -> Click two points to define X axis -> Choose the suitable Cartesian P1 direction (z axis) -> Escape
Or: Choose 3PointsXZ -> Define X axis by putting (1,0,0) -> Then define Z axis by putting (0,0,1) -> Escape

Data -> Conditions -> Volumes -> Geometry -> Polarization (Cartesian) -> Define Polarization (P2) (0,0,-1) direction

Assign Polarization (Local-Axes P1 and P2) -> Choose the volume -> Finish

MESHING

Cant view is not very suitable to Meshing -> View -> Rotate -> Plane xy (original)

Mapped Mesh

Meshing -> Structured -> Volumes -> Select all volumes -> Then Cancel the further process
Meshing -> Structured -> Lines -> Enter number to divide line -> Choose 2 &8 for the lines -> Generate
