Hi, I'm developing a hydrogen tank in which the hydrogen is removed according to the Fuel Rate(input port1).
The model is successfully compiled, but at time 217s the running stopped with warnings as follow
Here's the widow of Solver Profiler
Although I increased the number of consecutive min steps, it didn't work
I'm not familiar with the moist air system, coould anyone please tell me how to solve this problem?

Hello Guangwei
I think the model may have some issues. It looks like you are filling/emptying the chamber. This leads in the end to very high pressure or vacuum, which sets the model into an assertion.
One of the ports is not physically connected, it has just the property block attached. Try out modifying the model.
