I changed the temperature of the reservoir, but the interpretation is not converging.

Hello, I'm a student studying Simscape. I'm modeling the temperature change of hydrogen.

The initial temperature was 23K, which caused the temperature to change to 30K after exiting the reservoir and passing through the pipe. The temperature of 30K hydrogen was then set to rise to about 350K after passing through a heat exchanger containing helium.

However, setting the reservoir temperature of the hydrogen line to 30K after passing through the heat exchanger yields the desired interpretation result, but setting it to 350 K does not converge the interpretation.

I think it's right to set the temperature of the reservoir at 350 K, but I'd like to know which part is wrong.

What happens when you place the reservoir in A2-B2 circuit instead of A1-B1 circuit ? Does it has same convergence problem ?

I tried to replace it with the A2-B2 circuit, but it was confirmed that it did not converge.
