II. How To Use ATILA

3.2 Unimorph (2)
BOUNDARY CONDITIONS


PROBLEM - 3D Rectangular Plate, PZT4 and Brass = 40mm x 6mm x 1mm, Cantilever Support


BOUNDARY CONDITIONS
Polarization/Local Axes

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

Choose 3PointsXZ -> Define X axis by putting (1,0,0) -> Then define Z axis by putting (0,0,-1) -> Escape

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

Potential

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

Surface Contraints (Cantilever: One-End Clamp)

Data -> Conditions -> Surfaces -> Surface Constraints -> X, Y and Z components -> Clamped -> Assign left two surfaces

To check the assignment -> Draw -> All conditions -> Include local axes
