Issue with Sensitivity Analysis

[Priyam Nayak]

Hi Daniel,

I am trying to simulate formation of acetic acid from methanol. In the process, i was doing sensitivity analysis on the CSTR and trying to find how change "delta-T" for CSTR would change "mole fraction(mixture)-acetic acid" in the product stream will be affected. However, there seems to be no change. But when the outlet temperature is increased manually from CSTR calculation parameters which in turn change delta-T, then the molar fraction(mixture)-acetic acid in the product stream changes. Kindly look into the attached file.

Delta-T is not writeable (not used as an input for the calculation routine). On the next update you'll see the Outlet Temperature on the variable list, which you will be able to use instead.
