Run a simulink model for a certain amount of time and pause at T=0.5 more than 9h

hey everyone,
I've run my simulation in simulink but for more than 9h, the simulation is at T=0.5. How can I solve this problem (V 2018)

you are likely using a variable step solver and it is hanging on something. You need to find what is doing it, Switching to a fixed step solver isn't an ideal way to get around it, but will likely "jump" over the problem area. Can you share your model instead of a screen shot? It is likely the model needs to be modified or changes made to the solver settings.

based on the model, there are a few things. One, your discrete time step is far too large. It needs to be at least 100 times smaller than your switching frequency. So if your switching frequency is 1 khz, time steep needs to be 1/1000/100. Also, your PLL is causing problems with the simulation. In general, it looks like you've built too large of a model at once. You need to build a simpler smaller model that works, and slowly add complexity to it.
