Dear experts, I need help with a sensitivity analysis issue

Thread Content

I’m a beginner learning Aspen, using version 7.2. I encountered problems while performing sensitivity analysis. The model in question is a simple one that converts water at 25°C into saturated steam at 100°C; I was trying to analyze the effect of the inlet water temperature on the heat load. With the settings as they were, the analysis showed that the heat load was 0 in all cases, but when I checked the results from running the module, there was indeed a heat load. What could be the issue? Thank you

The tabulation settings are incorrect; they should be consistent with those used in the sensitivity analysis, and the duty value should be entered accordingly

There’s an issue with my variable settings; that dependent variable should be net-duty
