Custom annotation for non-standard experiment settings

[Francesco Casella]

If you select any option in the Simulation Setup of OMEdit which is not standardized in section 18.4 of the Modelica Specification 3.3r1 (i.e., anything besides StartTime, StopTime, Interval, Tolerance) and tick the checkbox "Save simulation settings inside model", those options are actually not saved. The next time the model is reloaded from file and simulated, those options will be re-set to default.

This is not a good idea: for instance, for non-stiff models using the default implicit solver dassl might introduce an unacceptable performance penalty, while an explicit solver could end up being much faster and less memory-consuming. It's really annoying if one has to set all those options manually every time.

I would suggest to introduce omc-specific vendor annotations to store all those extra settings.

Would a custom annotation also be a good place to define a default set of plots?

E.g. when I have a complex model that I am simulating and adapting/enlarging, every time I open the model in OMEdit, after first simulation, I have to hunt down the quantities I want to plot in the variables browser. If you have O(10) variables distributed over multiple plots, this gets old after a while.

It would be awesome if,when working in OMEdit, I could put in the modelica source something like annotation(Plot(mymodel.component1.port_a.m_flow, mymodel.component2.pressure, mymodel.controlsignal), ParametricPlot(mymodel.component3.T, mymodel.overall_efficiency)). Is there already a way to achieve this, that I failed to identify? Kinda feels like this [cs]hould be part of the experiment annotation, but it isn't, afaict.

Adrian told me he would talk to Per if he has some time to deal with this. Per, do you?

[Adrian Pop]

We talked internally and Adeel and Arun will work on this.

Ticket retargeted after milestone closed

[Francesco Casella]

It seems that this has been possible for a while, after #3488 was fixed, so I'll close this ticket.

[Christoph Buchner <buchner@…>]

Should I put the plot annotation proposed in comment:3 into a separate issue?

[Adeel Asghar]

Yes please create a new ticket for it.
Note that custom annotation should have a name like __OpenModelica_plot instead of Plot.
