II. How To Use ATILA

2.1 Magnetostrictive Rod (3)
PROBLEM TYPE


PROBLEM - 2D Cylinder, JM = 50mm L x 6.5mm dia

This example problem illustrates a coil energized with a current source inducing movement in a rod of magnetostrictive material. The magnetostrictive rod has a plane of symmetry normal to its axis. The rod can also be represented using an axisymmetric model. Therefore, only a quarter of the cross-sectional area of the rod needs to be used.


MESH GENERATION

Use a structured, quadrilateral mesh for the rod and the surrounding air.

PROBLEM TYPE
Data -> Problem data -> 2D, Axisymmetric, Harmonic, Click both Compute Stress and Include Losses

FREQUENCY
Data -> Interval data (10000-30000 Hz)

To obtain the more precise frequency dependence
Repeat Data -> Interval data -> Use New Interval -> Copy condition's entities from interval 1 -> Yes -> Create interval 2 -> 20000-24000 Hz -> Create interval 3 -> 15000-17000 Hz
