Mockup Practice in Tutorial

[corechang]

Hello,

I wonder if someone can help me to resolve my problem in following the Mockup practice in tutorial.
I checked all parameters and boundary conditions, but couldn't get the same result as one shown in tutorial.
For example, contour fills show that temperature became 100 °C in bentonite area, not only around the heater.
I am not sure what was wrong or missing. Please help.

I attach my file here. Since the file is over the max upload limit of 5 MB, I separate and put two files: simulation file and result file.

Thank you very much in advance.

Regards,
