I am using Lumerical 2024 R1.3 and have set up a simple model and am attempting to send a plane wave towards it, starting from some zheight above the model. However, every time I try to change the geometry by clicking Edit Source --> Geometry --> Apply, the settings automatically default back to zero and will not save my new inputs. I tried changing the plane wave geometry using a script, but that also did not work. Does anybody have suggestions for how to change the geometry and get around what seems to be a new bug in this version?

Same problem here with Lumerical 2024 R2.1. You can move it by clicking on the object and dragging it, but I don't know a way to do it precisely

OK, one workaround is that you can make a new group that contains just the planewave, and then do relative movements to the group to get precise changes. Hopefully the default size is big enough, I don't know a way to change that.

I found another workaround. You install a Gaussian source, and then edit the geometry in the Gaussian source. When you're ready to move to a simulation, change the source shape to a plane wave and the geometry will persist.

Oh that's much nicer, thank you

This happens for the specific version. Please download and install the newest version and it should work as expected.
