I do not understand PSUD's model enough to guess what the numbers should be.
I have tried to figure this out myself but haven't had any luck so far. If someone who actually
knows how to do this could at least point me in the right direction I would be greatful.
Better still, check if the values for the specific rectifier is correct or not.

Long before JLH wrote how PSUDII rectifier parameters were calculated.
This is for a tube rectifier, but it may help.

Some Lundahl chokes can be connected with " serial connection for improved common mode rejection " instead of usual serial connection. Is there any difference designing with PSUD?

PSUD unable to accept linked inductors.
If it is important for you, try another simulator (for example LTSpice).

PSUD2 does not know about common-mode noise, so just put a single choke in of the appropriate value.

Many thanks. Lundahl 1638 is 4HY, 18ohm. I have to use these values? ( or I have to double? )i

Which connection? If it has two windings, and you connect them in series then you get roughly four times the inductance of wiring them in parallel. This is still the case whether the two windings are right next to each other (conventional wiring) or in opposite legs of the PSU (for slightly improved CM rejection).
