yt.frontends.ramses.io.convert_ramses_ages(ds, conformal_ages)[source]¶

yt.frontends.ramses.io.convert_ramses_conformal_time_to_physical_time(ds, conformal_time: ndarray) → unyt_array[source]¶

Convert conformal times (as defined in RAMSES) to physical times.

Parameters:

ds (RAMSESDataset) – The RAMSES dataset to use for the conversion
conformal_time (np.ndarray) – The conformal time as read from disk

Returns:

physical_age – The physical age in code units

Return type:

np.ndarray
