Hello Julio,

You could use an initial condition appended to the capacitor value, see
the text below which is copied from the ngspice interactive help:

 3.1.4.  Capacitors

 General form:

     CXXXXXXX N+ N- VALUE <IC=INCOND>


 Examples:

     CBYP 13 0 1UF
     COSC 17 23 10U IC=3V


      N+ and N- are the  positive  and  negative  element
 nodes,   respectively.   VALUE  is  the  capacitance  in
 Farads.


      The (optional) initial condition is the initial  (time-
 zero)  value of capacitor voltage (in Volts).  Note that the
 initial conditions (if any) apply 'only' if the  UIC  option
 is specified on the .TRAN control line.
