I’m encountering problems during Aspen sensitivity analysis and can’t solve them; I need expert help
Thread Content
During the sensitivity analysis, the final results seem acceptable, but there are errors; I’m not sure what’s causing them. Could someone who is more experienced please take a look? (Version 8.4)
Could the poster describe the operating conditions? It seems that the temperature range is set too wide; within the range of 30–150°C, the flow rate for C stocks at temperatures above 109°C becomes 0. Errors also occur in this situation. By changing the temperature range to 30–110°C, no errors are reported anymore
The version is too high, making it difficult to open. Judging from the comments below, the temperature range is too large; it’s acceptable from a simulation perspective alone ； The actual process will not be affected by such large variations in the measurements.
The version is too high; it won’t open. However, the selection of variables for sensitivity analysis must be appropriate; it should not be conducted merely for the sake of sensitivity analysis. One needs to know what the purpose of the analysis is, otherwise it becomes too arbitrary!
