Hi，

The following is a section of the print file.My simulation time is 310e-6，time step is 2.0e-9. The simulation has run for 0.2876800E-03.However，it then reported error，like the following. What the meaning of this and why？

Another questions is that I don't the time ratio and the default should be 0.8， but the print file says the time ratio is 1.0 . WHY?

Best regards
