Runs on CoolSim’s new simulation service, once your account moves there

For an account moved to the new service at app.coolsimsoftware.com, the preview signs in, sends runs, follows them and stops them there. An account moves only when we invite you to set a password on the new service. Until then, the preview signs you in and runs your models exactly as your current CoolSim does.

Download Report opens those runs in CoolSim

For a run on the new service, Download Report fetches its report and opens it in CoolSim like any other. The report has the summary, the cooling unit and rack results, the sensor readings and the PDF, but not yet the temperature, pressure and airflow pictures. View Online is not available for these runs, and CRAC failure analysis does not run there yet.
