I am reporting some behaviors of which you may not be aware. The simulations are of a homogeneous reaction in a CSTR Unit. I emailed the files to you.
Problem 1 {CSTR (Forum) err=LS V1.0.fsd}
Changing mole fraction, x(CO2), from 0.35 to 0.36 yields the following message:
error: calculate failed for unit CSTR: Solution failed: line search did not converge
Problem 2 {CSTR (Forum) err=k V1.0.fsd}
Clicking on solve provides a different value of conversion, X(CO2), each time. Which conversion is correct, the first or the last?
While changing the reaction rate constant, k, different values of conversion, X(CO2), were obtained based on the previous result.
Are these just characteristics of the operation of COFE?
