Modules disrupted during simulation

.Net Add-on Programming
1

When I start the simulation in code firstly, it is ok. But it happens that all modules in the whole layout are disrupted when I start simulation secondly. Are there something I do not notice?

The code I used:

public void TestFun()
{
    ISimulation simulation = _application.Simulation;
    simulation.TimeMode = SimulationTimeMode.VirtualTime;
    simulation.Reset();
    simulation.RunTime = 100;
    simulation.SpeedFactor = 4;
    simulation.WarmupTime = 0;
    simulation.Run(100);

}

What exactly do you mean with “all modules in the whole layout are disrupted”

3

The position of components in the layout are disrupted

4

If the positions change on reset undesirably then you probably need to add a call to ISimulation.SaveState() before starting simulation, which saves the initial positions and such.
I think clicking the play-button in the UI calls SaveState() as well.

Thank you, it is solved
