Hi there! If you want to do CW propagation in the unidirectional pulse propagation mode, I'd suggest the following:
I attached a demo calculation in BBO, doing second harmonic of a 200 THz (~1.5 micron) laser. It's done in 3D so you can see the effect of spatial walk-off.
Does this make sense for you?
This works because in the UPPE mode, the time grid is periodic, so a CW beam with matching periodicity will propagate correctly. It will be trickier if you want to use the FDTD mode, since that requires a beginning and end time of the field...

could you provide a version for CW, I do not know how to fix it to CW SHG.
