Thank you, version 2.1.2 has been downloaded.
And yes, I logged in and then pressed the Run button, and the R2D folder was successfully created.
But when I run Example 2, it shows "Successfully obtained job status: FINISHED," but the results folder is empty and attached are some images that are displayed.
I then tried many other examples, most of the time without a result file. Only on one of these occasions did the result file appear when only two buildings were running.
This confused me and made me think that the results were random. Is this because of my Internet problem?
