Could not find a valid modelname

[pauledd]

Hi

I am quite new to simulation and I created a simple circuit…

I’ve some errors with the message:

Error on line 4 :
q2 net-_bt1-pad1_ net-_q1-pad1_ 0 bc337
could not find a valid modelname
Error on line 5 :
q1 net-_q1-pad1_ net-_q1-pad1_ 0 bc337
could not find a valid modelname

Can someone enlighten me whats the problem here?
I just used the BC337 from the Kicad shipped symbols…

I somehow solved it by adding this text to the schematic:

.model bc337 npn
now it simulates without errors
