The newFASANT utilities allows you to set up a remote server, use the batch utility to mesh and execute a project or upload a project
to a queueing system.
GTD-PO combines the GTD and PO high-frequency techniques for the RCS analysis of complex bodies as well as antenna
and radio propagation in large urban environments.
In this example, the Monostatic RCS of a plane is calculated. The normal vectors of
the geometry are duplicated for this simulation.
Step 1
Start newFASANT.
Step 2
Select File and click on New.
Step 3
Select PO.
Step 4
Click on Geometry → Surface → Plane, which introduces the first and the second point
dialog as shown in the next Figure.
In this example the user enters the following parameters into the command line:
First corner of plane: -0.5 -0.5 0
Plane size [width depth]: 1 1
Step 5
Click on Simulation → Parameters.
Step 6
Select 1 bounce (simple reflection) and a frequency of 0.3 GHz as shown and
left-click the Save button.
Step 7
Select RCS → Parameters.
This command appears in the top left side of the newFASANT window as shown in the next Figure.
Step 8
Select Monostatic RCS only, and left-click on the Save button.
Step 9
Select Output and left-click on Observation Directions.
Step 10
Introduce the far-field observations (cuts, points and sweep angles), as shown in the
next Figure and left-click on the Save button.
Step 11
Before running the case, select Meshing → Create Mesh.
Step 12
Select 1 processor and define the curvature mesh option with a distance error of 10
and surface error of 0.08 and left-click on Mesh.
Left-clicking on Mesh enables the meshing engine as shown in the next Figure:
In order to visualize the mesh, then Meshing → Visualize Existing Meshing and select
the .msh file.
Step 13
Select Calculate → Execute and then indicate the a number of processors available to
simulate this case.
Step 14
When the simulation finishes, we can visualize the simulation results. Click on Show
Results → Far Field → View Cuts, which allows the user to show the RCS graphic (in
the next figure).
Step 15
Click on Show Results → Far Field → View Text Files. Then select the Steps and the
order and press OK to show the RCS data file.
This example has been executed using a plane whose normal vector is along the Z-axis.
The user can duplicate this vector and simulate the problem again using duplicate
normal vectors. After the simulation, the user can visualize the results to
see the differences between one normal vector and two duplicated normal vectors. To
view the normal vectors of this geometry, click the icon, as shown in the next
Figure.
Step 16
To duplicate the normal vectors click on Simulation → Duplicate Normals.
Then select the object to duplicate the normal vector and left-click the Add button
in the right panel that has appeared.
Step 17
Re-mesh the geometry and start the simulation again, like in step 12 and 13. The
process is simply the same.
Step 18
Click on Show Results → Far Field → View Cuts, to show the RCS graphic like in step
14. In this case, we can notice that the result is different.
