Getting the error "No simulation found. Please add at least one simulation!"

[mercmobily]

I am trying to run a simulation. This is my settings screen:

The simulator's output directory exists:

~$ ls -l /home/merc/.qucs/spice4qucs
total 8
-rw-rw-r-- 1 merc merc 292 Jun  9 23:45 spice4qucs.cir
-rw-rw-r-- 1 merc merc  88 Jun  9 23:45 spice4qucs.cir.dc_op
~$ 

ngspice runs:

~$ /usr/bin/ngspice

What am I doing wrong?

This question was asked and answered several times. Do literally what the error message says. Add at least one simulation on the schematic. The simulation is a special device that could be found in the left panel in the "simulation" group. This procedure described in a tutorial document. Please read this documentation.
