Electromagnetic Optimization and Tuning (4)
 Defining v1 and v2 as variable 1:





Open edge_fed_rpatch1.geo. Select Edit->Select Vertices. Window v1 and v2.
Select Optim->Variable for Selected Objects. Enter Tuning Angle = 90. Select
OK. MGRID will be waiting for you to define the Low Bound and High Bound.
Move the mouse downward and click. Enter the Low Bound as -40.
Move the mouse upward and click. Enter the High Bound as 70. Be very careful
not to let the Y of v2 to be above that of v4 when you define the High Bound.
Select OK to finish the definition. MGRID will warn you not to change the
geometry anymore.
Defining v1- v6 as variable 2:
– Select Edit->Select Vertices. Window v1 to v6.
Select Optim->Variable for Selected Objects.
Enter Tuning Angle = 90. Select OK.
– Move the mouse downward and click. Enter
the Low Bound as -30. Move the mouse
upward and click. Enter the High Bound as 30.
As you can see, no matter what Low Bound we
define, it will not cause the Y of v2 to be larger
than the Y of v4.

Save as: edge_fed_rpatch1_optim.geo.
v6
v3
v4
v1
v5
v2
Note: Try to define smaller range between Low Bound and High Bound for faster optimization.
