System not converging / generator power increasing far too much.

[oh304]

Hi there,

I am simulating a helium primary loop, heated by a reactor core, which is then linked to a secondary loop almost entirely copied from the closed brayton example in MOOSE. Things seem to work OK so far, however, the generator power is increasing extortionately and I cannot understand for the love of god why! If anyone would like to help that would be greatly appreciated.

Below is the example I used to build the secondary loop.

If you are interested in checking out the system, I have dropped it in this github repo below:

All the best,

Hi Oscar,
I think we exchanged a few emails. Hope the VTB example will help.
