Aspen Convergence Tolerance ?

[Clay]

Dear all,

[link Point to another website Only the registered members can access]
I did a simulation using Aspen plus. I have some questions about solver.
First I would like to know what represent the values of the column Error/Tolerance, anyway they do not correspond to the tolerance values (Please look at the attachment)

Then i do not understand why the solver stopped at the 242 iterations without achieving tolerance? (max iterations:1000)

Thanks in advance.

i see all of your variables have converged, that's why the solver stopped.

about the error/tolerance, in aspen plus you can set the tolerance under Convergence/conv option...
and the error equation is (Xcal-Xassumed)/Xassumed
