Create a new newFASANT project. To do this, select the
File → New option (alternatively, the press Ctrl+N).

Step 3
After selecting the New option, a list of the available modules is presented. The
user needs to select a module from the available module list. Select MONCROS for
this training example.

Step 4
Select the Geometry → Surface → Plane option.\

Step 5
The command line panel requires some parameters at this point. Enter “-0.5 -0.5 0” as
the first parameter and “1 1” as the second parameter so we create a 1x1 plane
centered at the origin.

Step 12
Leave the default observation directions (0.0 phi cut with theta angle varying
between 0.0 and 180.0 using 181 samples).

Step 14
Set 10 divisions on planar and curved surfaces, set Processors to 1 and the default
number of bands per octave. Press the Mesh button.

Step 16
When the simulation finishes (the progress bar on the bottom-left corner displays
“Done”), we are able to see the results. Select the Show Results → Far Field → View
cuts option to show the RCS plot.
