Dear Mr Adrian Pop:

I started using this editor with the following example of an RL circuit
http://yma7xa.bay.livefilestore.com/y1p … png?psid=1
and the simulation of it was
http://yma7xa.bay.livefilestore.com/y1p … png?psid=1
the same simulation with Shell OpenModelica us results in a zero current at the beginning.
Which the reason for this difference in response?
Yours sincerely,

I performed the following simulation,

corresponding to the picture below,

http://ymauxa.bay.livefilestore.com/y1p … png?psid=1
the code is,
model mecanico4
  Modelica.Mechanics.Translational.Fixed fixed1 ;
  Modelica.Mechanics.Translational.Fixed fixed2 ;
  Modelica.Mechanics.Translational.SlidingMass slidingMass1(L=0, s(start=0.1));
  Modelica.Mechanics.Translational.SlidingMass slidingMass2(L=0, s(start=0.6));
  Modelica.Mechanics.Translational.Spring spring1 (c=1000) ;
  Modelica.Mechanics.Translational.Spring spring2 (c=15);
  Modelica.Mechanics.Translational.Spring spring3 (c=1000) ;
equation
  connect(spring1.flange_b,fixed1.flange_b) ;
  connect(slidingMass1.flange_b,spring1.flange_a) ;
  connect(slidingMass1.flange_a,spring2.flange_b) ;
  connect(slidingMass2.flange_b,spring2.flange_a) ;
  connect(slidingMass2.flange_a,spring3.flange_b) ;
  connect(spring3.flange_a,fixed2.flange_b) ;
 
end mecanico4;

if I make the simulation for 10 seconds, the graph is,

if the simulation up to 80 seconds, the system behaves as expected,

when it reaches a simulation time of 100 seconds, the behavior is different,

may be due to this, or is correct?

I say goodbye to you carefully
