Pull request overview

This PR adds a new ABM (Agent-Based Model) logger for tracking new infections per location type per age group (LogInfectionPerLocationTypePerAgeGroup), integrates it into ResultSimulation via a new history_detailed history and get_result_detailed() method, updates the abm_parameter_study.cpp example to save both standard and detailed results, and introduces a new Python plotting module (plotAbmInfectionStates.py) with tests for visualizing the results.

Changes:

Added LogInfectionPerLocationTypePerAgeGroup (and unused LogInfectionStatePerAgeGroup) logger structs in common_abm_loggers.h
Added m_t_prev tracking to Simulation class and integrated the new detailed logger into ResultSimulation
Updated abm_parameter_study.cpp example to collect and save both aggregated and detailed results in separate subdirectories
Added new Python plotting module plotAbmInfectionStates.py with functions to visualize infection states and infection-by-location-type data, plus unit tests

Thanks, I have a few comments which should be discussed/resolved.
Furthermore, I think fixing #1406 here would make a lot of sense.

DavidKerkmann · 2026-10-08T11:22:57Z

    mio::History<TimeSeriesWriter, LogInfectionState> history{
        Eigen::Index(InfectionState::Count)}; ///< History used to create the result TimeSeries.
+
+    mio::History<TimeSeriesWriter, LogInfectionPerLocationTypePerAgeGroup> history_detailed{
+        Eigen::Index(LocationType::Count) *
+        this->get_model().parameters.get_num_groups()}; ///< History used to create the detailed result TimeSeries.


I find it a bit unclean that we have a hardcoded result_simulation which is tailored to the one example (parameter study) with these particular loggers/histories.
It would be better to have a framework that allows us to do the parameter studies in a way where the make_model and the history(-ies) is/are provided instead.

Agreed. I reverted ResultSimulation to main and moved the study-specific histories into a small StudySimulation wrapper in the example.

I think this might be the way to go. We could consider moving the result_simulation to the example as well. I would like to discuss this with @reneSchm (perhaps tomorrow).

…on logger - Revert ResultSimulation and Simulation to main; the parameter study example now uses a small StudySimulation wrapper holding its histories. - LogInfectionPerLocationTypePerAgeGroup keeps its previous log time and location types itself and attributes new infections to the location where the interaction happened, not to where the person moved afterwards. - Gather the detailed results across MPI ranks by returning them from the processing lambda. - Handle the IOResult of save_result instead of discarding it. - LogInfectionState counts in a single pass over all persons (#1406).

also I made a new PR request for #1406
for this logger, which is the inly one that uses it, LogInfectionState, to be independent of it.

DavidKerkmann

Thank you for the quick changes!
I think we should discuss a few things regarding the logger, otherwise it looks good!

- LogInfectionPerLocationTypePerAgeGroup remembers the InfectionState, LocationType and PersonId of each Person at the previous log, instead of the previous time. This removes the dependence on a start time of 0. - Persons without a previous log, at the first log or added since the previous log, are not counted but tracked from then on. An entry is only used if it belongs to the same PersonId. - Test a Simulation not starting at 0 and a Person added during the Simulation.
