Errors management/reporting

Reported by: Rafael Winck Espinoza Owned by: Rafael de Pelegrini Soares
Priority: major Milestone:
Component: EMSO Version: 0.9.50
Keywords: Cc:

Description

The attached flowsheet causes an error which blocks EMSO functionality, doesn't allowing, for instance, the use of STOP button, that just doesn't work.

In this cases it's necessary to close the aplication. Even so, a 'Close error' message appears, demanding closing by the task manager Windows tool.

Dear Rafael,

I reproduced the problem you reported and I'll check what is happening.

Paula has helped me to find another set for this flowsheet, so it is already running. Therefore is interesting to understand the trouble in order to improve the error reporting and fix such bugs!

Fixing this kind of problem would be very important because it happens very often at some settings for the attached flowsheet, bringing difficulties to handle with the application.

I think I solved the problem.

Now when running the model you've attached (I just changed the initial conditions to get convergence) the simulator produces the following output:

...
Intermediate step: 123.358
Intermediate step: 124.061
Variable Had_reb crossed bounds, lower:-1e-06 value:-0.00185526 upper:1.00001
Intermediate step: 124.061
Variable Had_reb crossed bounds, lower:-1e-06 value:-0.00185281 upper:1.00001
Bounds are impeding progress!

Checking bounds ...
Had_reb at lower bound: -1e-06
Variables at bound, this maybe the source of the problem.
Simulation of 'Coluna_24T04' finished with an *error* in 6.96044 seconds!

It will be available on the next release.

You mean that there was really a problem with the EMSO code, not only in the flowsheet?

Yes, there was a problem with the EMSO code: instead of reporting the problem in the FlowSheet? it stops working without giving a reason.

Unfortunaly the trouble still remains in version 0.9.51; I've found it again with others conditions in that same flowsheet.

P.S.: Version 0.9.51 doesn't appear in the list box of ticket properties.

Dear Rafael,

Could you please update the FlowSheet? attached for the exact situation where the problem shows up?

Thank you for reporting, I fixed that.
