Recently, I have been working on an optimization study using Archsim with Octopus. While during the automatically optimization process, I find that my output selection defined in the output selection window always disappear, which led to the “mass addition” component failed to collect data, and therefore influence the optimization results. I guess this problem may comes from some bad solutions in the process of many iterations, when a combination of parameters can’t work well (such as too many iterations in Airflow Network), then maybe the selections in output selection window will be invalid and then disappear, and the next round of calculation will be abnormal. This problem has been bothering me for a long time, but I don’t know how to solve it. Can you help me and give me some advice?
