Never ending calculation process

Post by rawatamm »

Dear Code_Bright Support Team

I have to simulate the heating test experiment with 80 °C. The problem is modelled as axis symmetric abt Y axis. The calculation process is not ending since days. I am not able to find the problem.

The file is attached with this message.

Please guide me on this issue. This will be a great help.

Dear rawatamm,

It seems that you are producing abrupt changes in temperature and liquid pressure in your model, which make really difficult to the numerical approach to find a solution. You would need to make those changes more progressive in order for the model to be able to converge. Think that in real life, changes are also relatively progressive. It is impossible to set a flux or a temperature immediately. It will always take some time.

Regards,

Alfonso
