I am trying to set first two modes for the port with a code

fdtd.addport()

fdtd.set("name","output_port")

fdtd.set("x",3*unit)

fdtd.set("x span",0*unit)

fdtd.set("y",2*unit)

fdtd.set("y span",3*unit)

fdtd.set("z",0*unit)

fdtd.set("z span",2*unit)

fdtd.set('mode selection',(1,2))

 

which does not work. I have tried also with [1,2], without success. How can I reach this?

 

Setting only one mode works perfectly fine, with, eg.

fdtd.set('mode selection','fundamental TM mode')

Hello,

you can find more details here : updateportmodes – Script command – Ansys Optics

Actually, I get with

fdtd.updateportmodes(1,2)

an error:

lumapi.LumApiError: “argument list for the updateportmode is incorrect – updateportmodes arguments were converted to (‘int, ‘int)”

fdtd.updateportmodes([1,2]) also does not work with an error:

 

”lumapi.LumApiError: ‘argument list for the updateportmode is incorrect – updateportmodes arguments were converted to (cell array)'”

I have solved the issue, one should use

fdtd.set('mode selection','user select')

fdtd.set("selected mode numbers",np.array([1,2]))

Hello Nina, thanks for the update.

We cab also use:
fdtd.updateportmodes(np.array([1,2]))
