@liwenjia12: Please see our debugging guide for some tips.

The problem could be in many areas, perhaps your CO2 emissions or initial conditions are incorrect.

Also, please know that we are unable to provide assistance with validating your results scientifically.

liwenjia12 commented 1 year ago

So I want to Know where can I change the initial conditions
