Problems encountered when simulating the RPLUG reactor

2009-11-27View Original

Thread Content

When I was simulating the RPLUG reactor, errors appeared in the convergence and model analysis tools sections after performing the calculations. What could be the cause of this? Please give me some advice! Some of the error messages are as follows: Beginning Convergence Loop $OLVER01 Method: SECANT Converging specs: DS-1 Block: B1 Model: RPLUG >> Loop $OLVER01 Method: SECANT Iteration 1 1 vars not converged, Max Err/Tol -0.11200E+06 Block: B1 Model: RPLUG >> Loop $OLVER01 Method: SECANT Iteration 2 * WARNING SPEC FUNCTION NOT CHANGING, POSSIBLY HAS A FLAT RESPONSE TO THE MANIPULATED PARAMETER WITHIN THE GIVEN BOUNDS. 1 vars not converged, Max Err/Tol -0.11200E+06 >> Loop $OLVER01 ended because of error. ** ERROR Convergence block $OLVER01 did not converge normally in the sensitivity pass on row 11 ** ERROR SOME ROWS COMPLETED WITH ERRORS. ** ERROR Convergence block $OLVER01 did not converge normally in the final pass

Woo woo woo woo! No one told me, so I had to figure it out on my own! ! ! ! 11 1# wwzyx1983

The question posed by the original poster is too abstract; it’s difficult to know how to help. It’s suggested to turn off the analysis tools first, and see whether it’s the process that isn’t converging or the analysis itself that isn’t working, before trying to find solutions to each issue individually

If the original poster has not resolved the issue, it is recommended to share an example, as this will help in answering the question

I know which problem you’re facing. Take a close look at the results that you’ve hidden – it seems that C6H10 isn’t being produced at all. In other words, there’s an issue with your reactor; therefore, no matter how you adjust the molar flow rate of the feed material, the final result won’t change, let alone meet the requirements specified in the design
