Hi there

I cant seem to find an appropriate solution to my problem on this forum so I have decided to post a new thread about this.

I am working on a supersonic flow from a nozzle into an ambient control volume. But what happened is whenever I used standard initilization computed from the nozzle inlet, divergence will occur instantly and I cant run. However, when I used hybrid initialization, the solver managed to run.

So what is the difference between the 2 kinds of initilization? Not in terms of its mechanism (kind of read about how these 2 initilizations work from the manuals) but in terms of its outcome/ robustness/ accuracy?

Cos I was told that standard initilization would be a better option than hybrid.
