Dependent variable shape access from within SingleArcPropagator #179

Closed alopezrivera closed 1 year ago

alopezrivera commented 1 year ago

Context

Hi! First of all, thank you for your work! For context, I use tudat through the Python tudatpy interface. If any reference to an object or function I make is not clear it may be due to this, please let me know and I'll clarify as needed.

Tudat allows to store a breadth of dependent variables in simulations. Currently, it is possible to access the string ID of each of these dependent variables directly from within the SingleArcPropagator object obtained from the propagation (in tudatpy, returned by tudatpy.kernel.numerical_simulation.create_dynamics_simulator).

Need

It would be very useful to have access to the shape of the dependent variables that are being saved (scalar, vector, matrix), besides their ID. This information is contained inside the SingleDependentVariableSaveSettings objects given in tudatpy to the tudatpy.kernel.propagation_setup.propagator.translational function, and is accessible as an attribute of those objects at least in C++.

Request

It would be very appreciated to

Required functionality should now be available through the following updates:

https://github.com/tudat-team/tudat/pull/181 https://github.com/tudat-team/tudatpy/pull/111

A few additional tests need to be run, but you can use it for development purposes for now.

Functionality is now merged, and a new issue with a loose end is opened here:

https://github.com/tudat-team/tudat/issues/182

the remaining open issue already existed before the modifications in the above pull request, so there's no reason not to merge these ones already
