Hi
I am trying to learn how to use QUCS-s on linux with ngspice backend.
My simulation is attached. I am trying to add a DC simulation of a simple transistor powered RC oscillator circuit. However, I get the error
Ngspice started...
Error on line 11 or its substitute:
q2 v2_out _net2 0 1
could not find a valid modelname
Simulation interrupted due to error!
Note: No ".plot", ".print", or ".fourier" lines; no simulations run
Note: No compatibility mode selected!
A picture of how I set out the simulation is also added.

Can anyone please tell me where I am wrong? Thank you.
