3.2 Unimorph (3)
MESHING PROBLEM TYPE VIEW RESULTS


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


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 "1" for all lines (which makes the thickness line no division) -> Choose 2 for only the right and left lines -> Choose 4 for only the top and bottom lines -> Generate

Mapped mesh (good)

PROBLEM TYPE
Data -> Problem data -> 3D, Harmonic, Click both Compute Stress and Include Losses

CALCULATION
Calculate -> Calculate window -> Start
POST PROCESS/VIEW RESULTS
Click for Opening the Post Calculation (Flavia) Domain
Notice the new Toolbar appearance
Click Admittance/Impedance Result
Admittance Peak Point : 4500 Hz -> This peak corresponds to the First Resonance

View Animation - Vibration Mode at a Particular Frequency
View results -> Default Analysis/Step -> Harmonic-Magnitude -> Set a Frequency
(100 Hz for Off-Resonance Mode: Peak Point : 4500 Hz for Resonance Mode)
Double Click Loading frequency: 4500 Hz Harmonic Case -> Click OK (Single Click and Wait for a while!)
Set Deformation -> Displacement
View results -> Deformation -> Displacement
Diformation Scale Change
Click Windows -> Deform mesh -> Change the Factor in Mesh Deformation
Other parameter than Displacement
Set Results View -> View results -> Contour Fill -> Von Mises Stress
After setting both “Results view” and “Deformation” -> Click to see the Animation
