You can set the
to true on the integrator object. You can get the integrator object from the roadrunner model via model.getIntegrator()
This will return variable time steps with the timepoints corresponding to the solver timepoints (these are not equidistant!).
These time points are the timepoints which guarantee the absolute and relative solver tolerances.
There are options to get denser timepoints:
1. make the tolerances more strict, which will produce more time points
2. perform interpolation on the variable timepoints timecourse.
I am mainly doing the option 2. when needing additional time points, e.g. for parameter fitting.
I.e. I am doing a variable time course simulation and then interpolate the time points I need.
(internally roadrunner is also interpolating the variable timecourse to get the equidistant time courses.
