VolumeJunction problem in THM

[SomnusYu]

Hi @joshuahansel and @GiudGiud ,

I'm doing the loop simulation in PWR using THM. Now, I just simulate a part of this PWR, including the downcomer, pipe, and low plenum, as shown in the picture:

But the solver did not converge. I tried a lot of ways to fix this problem, but nothing changed. I have no idea how to solve this problem. Could you please help me?

Here is my input file:

Hello

I'm on travel right now and won't be able to look at this for another two weeks.

Do we have access to your application ? I don't remember

Did you follow the troubleshooting failed solves instructions on our website?
