II. How To Use ATILA

2.1 Magnetostrictive Rod (1)
GEOMETRY MATERIAL ASSIGMENT


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.


GEOMETRY/DRAWING

Create Surface Simple structure list

Geometry -> Create -> Object -> Rectangle -> Enter first corner point-> 0,0 -> Enter second corner point-> 50,16.25 -> Enter

Geometry -> Edit -> Divide -> Surfaces -> Near point -> Select the Surface -> Choose NURBS sense -> V-sense -> 25,0 -> Select now the two surfaces -> Choose NURBS sense -> U-sense -> 0,3.25

MATERIAL ASSIGMENT
Magnetostrictive Materials

Data -> Materials -> Magnetostrictive -> JM -> Assign -> Surfaces -> Pick a Surface

Magnetic Materials

Data -> Materials -> Magnetic -> Air Mag -> Assign -> Surfaces -> Pick three outer regions
Click Draw -> All materials -> Check the material is assigned as JM and Air Mag
