<\/p>\nI set the dimesnions of the plane wave through script but when I ran the simulation, the dimensions of the plane wave change back.<\/p>\n
<\/p>\n
In the picture is shown after I set it through script but when I ran the simulation, the plane wave becomes wide again<\/p>\n

When running the simulation it changes back again and doesn’t keep the dimensions I have set up through script. <\/p>\n
Here is the example script:<\/p>\n
<\/p>\n
switchtolayout;<\/p>\n
redrawoff;<\/p>\n
deleteall;<\/p>\n
<\/p>\n
addfdtd;<\/p>\n
set(‘dimension’,1); <\/p>\n
set(‘x max’,50e-6);<\/p>\n
set(‘x min’,0e-6);<\/p>\n
set(‘y’,0);<\/p>\n
set(‘y min’,-2e-6);<\/p>\n
set(‘y max’,2e-6);<\/p>\n
set(‘z’,0.0e-6);<\/p>\n
<\/p>\n
set(‘mesh accuracy’,8);<\/p>\n
set(“mesh refinement”,”conformal variant 0″);<\/p>\n
set(“mesh type”,”uniform”);<\/p>\n
set(“dx”,20e-6);<\/p>\n
set(“dy”,20e-6);<\/p>\n
<\/p>\n
addplane;<\/p>\n
set(“name”,”plane wave”);<\/p>\n
set(“injection axis”,”y”);<\/p>\n
set(“direction”,”backward”);<\/p>\n
set(‘x’,30e-6);<\/p>\n
set(‘y’, 1e-6);<\/p>\n
set(‘x span’,20e-6);<\/p>\n
set(‘z span’,2-6);<\/p>\n
set(‘z’,0.0e-6);<\/p>\n
