Model did not solve period #491

Hello, everyone! I added the XML file of China's carbon emission constraint to the original configuration file based on GCAM-China. However, there are some problems in the process of solving the model. As shown in the figure, Image

Since "Ints" in my configuration set "Value name="stop-period">-1</Value", I still got the model result in the end despite several unsuccessful period solving results. And can be successfully opened in ModelInterface.

In this case, my confusion is:

  1. Are the results of the model reliable? I think that failure to solve in a period means that in this period, supply and demand are not in balance. When the model uses the data of this period to run next period, will it get a wrong results because it uses the wrong preivous data, even though the next period can be iterated successfully?

2 What useful information can this error give us to modify the added constraint. xml file to avoid this problem the next time we run-gcam?
