I ran a large model in the DTK.
It finished succesfully :), but the the 'run details' there is a line:

2025-05-15 10:53:40,839 [rtctools][MainThread][optimization_problem.py:205][ERROR]: Solver succeeded with status Time limit reached (600.208776842 seconds).
2025-05-15 10:53:40,841 [rtctools][MainThread][optimization_problem.py:217][INFO]: Done with optimize()
2025-05-15 10:53:40,842 [rtctools][MainThread][single_pass_goal_programming_mixin.py:434][INFO]: Done goal programming

Is that of any concern? 'Time limit' and ERROR is only mentioned in this line.

@KobusVanRooyen can you check this?

Run details.txt

The full run details are her.

I will have a look at this. Thanks for reporting this @samvanderzwan and @ladderup

@samvanderzwan and @ladderup this optimization was not successful and it should have error exit, but it did not. The results from this run should not be used, and it should be redone. This should be fixed in MESIDO and a issue has been created for this Multi-Energy-Systems-Optimization/mesido#292. Thanks for this feedback @ladderup

In summary the time limit was an issue. The optimization was almost done, but not fully completed. Two potential solution: increase the time limit a bit (before error exit, but wil become an issue again with other networks with the open source solver) or wait for the commercial solver (still to be made available in DTK) which should be able to solve the network within the current time limits. @samvanderzwan can you please advise?

@ladderup can you share the esdl file for this one please

@ladderup
If the ESDL file is available, I could also test the model with the latest version of Highs.

[ladderup]

Hi,
I managed to execute te optimization by extending the time_limit her:
grow_workflow.py
line 299: highs_options["time_limit"] = 600 >> 3600

Hi @ladderup

Thanks for the update. This is great news!
Test cases like this one could help us investigate ways to fine-tune the solver or adjust the model to reduce the runtime. It would be great if you could share the ESDL with us.
