Discontinuous plot in time domain simulation

[seedpower]

import andes

ss = andes.run(andes.get_case("ieee14/ieee14_full.xlsx"), setup=False, default_config=True)

ss.add("Fault", dict(bus=9, tf=1.0, tc=1.5))
ss.setup()
ss.PFlow.run()

# tf = 2.0s
# ss.TDS.config.tf = 2.0
# ss.TDS.run()

# tf = 3.0s
ss.TDS.config.tf = 3.0
ss.TDS.run()
ss.TDS.load_plotter()
ss.TDS.plotter.plot(ss.GENROU.delta)

I got the picture below:

Now, if I uncomment tf = 2.0s code

# tf = 2.0s
ss.TDS.config.tf = 2.0
ss.TDS.run()

This picture is :

Compared with them, they look a little discontinuous at t = 2.0s.

When I turn ss.TDS.config.tstep down，the discontinuity between them would be smaller. But it will take more time.

Q1: Whether this discontinuity will affect the time-domain simulation results?

Q2: Is there a better way to avoid this discontinuity without modifying ss.TDS.config.tstep?

This seems to be an issue in how the program resumes a simulation. The two are probably off by one step. Let me check that and come up with a fix.

Please fix it as soon as possible. I need the diagram made by it. I'm looking forward to it.

I'll work on it over the weekend.

Issue fixed in cuihantao@8f17167. Thank you for reporting.

Mind sharing what project you are using ANDES for?

Thanks for your repair, it works very well. I use ANDES for reinforcement learning. The software is great.
