Periodical Structures 6.3

14.1. Example 1: Analysis of a cell with Disk geometry

STEP 1. Start newFASANT. 

STEP 2. Select File and click on New. 

STEP 3. Select Periodical Structures.

 

STEP 4. Select Centimeters units.

 

STEP 5. Click on "Cell → FSS Primitive → Disk", which requires the center and the radius, as shown in the next figure.

In this example the user enters the following values:

  • Center: 0 0 0
  • Radius: 0.5

 

STEP 6. Click on "Geometry → Point → Single point", which requires the x,y and z coordinates as shown in the next figure.

In this example the user enters the following values into the command line:

  • Select point on screen [x y z]: 0 0 0.5

 

STEP 7. Click on "Cell → Define cell". Assign the material of the layer.

 

STEP 8. Click on "Simulation → Parameters". Configure the simulation with this parameters:

  • Units: GHz
  • Initial frequency: 10
  • Final frequency: 16
  • Samples: 4
  • Planewave Definition: Symmetric

 

STEP 9. Before running the case, select "Meshing → Create Mesh".

 

Configure the meshing with this parameters:

  • Planar surfaces: 40
  • Curved surfaces: 40
  • Mesh mode: Frequency, 16.0 GHz
  • Processors: (Processors available)

 

Click on "Mesh" button launch the meshing engine as shown in the next figure:

 

STEP 10. Select "Calculate → Execute" and select the number of processors available.

 

 

STEP 11. When the simulation finishes we can visualizethe simulation results. Click on "Show Results → View Cuts By Frequency".

 

STEP 12. To view text file results, click on "Show Results → View Text Files".
