Description

This is more of a philosophical issue. From my point of view, initial conditions are more related to particular runs of a given model than to the general definition of the dynamics and parameters. In other (code) words:

<Parameter name="x0" description="initial condition"/>
...
<OnStart>
            <StateAssignment variable="x" value="x0"/>
</OnStart>

and then define x0 in each run. It would be interesting having mechanisms to grab initial conditions from data files, possibly generated by a previous simulation. That would require the definition of a standard format for storing timeseries.

Research direction

No files, tests, or entry points are mentioned. Begin by locating the handling of Parameter, OnStart, and StateAssignment in the Java interpreter, then clarify the proposed per-run input and timeseries format requirements. Done would require an agreed design and implementation scope rather than a small isolated edit.
