Scalar BEC DataManager

The scalar BEC DataManager handles the wavefunction, grid, and parameter data of the simulation. To instantiate a DataManager object we simply call the constructor

DataManager(filename, data_path, wfn, params)

This object handles all the data of the simulation, including the wavefunction, grid, and parameter data.

We provide the filename and data_path at the creation of the object, and additionally pass in the Wavefunction object and params dictionary, which is then stored throughout the simulation.

Class methods

During evolution

The function that saves the current wavefunction data to the file is

DataManager.save_wavefunction(wfn)

Saves the current wavefunction data to the dataset.

You can call this function as often as you’d like depending on the time resolution you require.

Note

Since the wavefunction array is defined on a CUDA device, the data has to be passed over to the CPU to be saved. This slows down the simulation time, so only save data as often as you need to.
