II. How To Use ATILA

4.1 Rosen Type Transformer (3)

MESHING

Mapped Mesh

Meshing -> Structured -> Volumes -> Select all volumes -> Then Cancel the further process
Meshing -> Structured -> Lines -> Enter number to divide line -> Choose "2, 4 or 6" for the lines -> Generate

Use the higher number such as 2 or 4 for the higher accurate calculation.

ATILA requires that the mesh be composed exclusively of second order elements. The corresponding setting can be found under the Meshing menu. Select Quadratic Elements, then Quadratic. Note that this option is automatically set when you start the ATILA-GiD interface.
For the transformer, we will define a structured mesh. Select Structured | Volumes from the Meshing menu.

Apply this meshing condition to all the volumes in the geometry.

Then, define the number of subdivisions on all lines. Define 2 subdivisions along the thickness of the transformer.


Next, impose 4 subdivisions in the width of the transformer.


And finally, define 6 subdivisions along the length of each section of the transformer.


To construct the mesh, select the Meshing command from the Meshing menu.

GiD asks for a default element size, which, here, is of no importance since the whole geometry will receive a structured mesh. You can therefore use any arbitrary value, the mesh will be the same.

When the meshing is complete, GiD displays information about the number of nodes and elements that were generated.

The resulting mesh is shown in the next figure.
