Inductor dc resistance simulations
Then calculated the dc resistance with R_dc=Vdc/I


Yes, this is correct.

It might be marginally better to simulate with a current source, so the simulation doesn't blow up in case the inductor model has 0 dc resistance.

And of course this tells you what the resistance is in the simulation model. It doesn't necessarily tell you what the resistance of a real device would be, unless you've actually input good values for the simulator to calculate from.
