Simscape- Moist air error. Temperature at port B must be less than or equal to Maximum valid temperature.

</matlabcentral/answers/uploaded_files/139526/emosit_air_model.PNG> Attached image is my basic model, why am i getting assertion error.

An error occurred while running the simulation and the simulation was terminated Caused by: ['moist_air/Solver Configuration']: At time 134.033551, one or more assertions are triggered. See causes for specific information. Temperature at port B must be less than or equal to Maximum valid temperature. The assertion comes from: Block path: moist_air/Controlled Volumetric Flow Rate Source (MA).

Temperature at port A must be less than or equal to Maximum valid temperature. The assertion comes from: Block path: moist_air/Pipe (MA)1.

Please someone can help me with this?

Hello Sachin,

One possibility is that the constant flow rate is causing a pressure rise in the Constant Volume Chamber. As the system keep trying to push the same flow into the chamber, the compression accompanies a rise in system temperature. Eventually this reaches the maximum setting for the network.

Try looking at the logged data to see if you see such a phenomenon happening.

Hello Martin , how to deal with this phenomennon, limt flow rate modify some parameters in Flow rate sorce? Thanks!
