Initialize a Solution object.

Parameters:

  • name (str) – The name of the solution.

  • total_mass (str or pint.Quantity, optional) – The total mass of the solution.

  • total_volume (str or pint.Quantity, optional) – The total volume of the solution.

  • masses (dict, optional) – A dictionary of component masses.

  • volumes (dict, optional) – A dictionary of component volumes.

  • concentrations (dict, optional) – A dictionary of component concentrations.

  • mass_fractions (dict, optional) – A dictionary of component mass fractions.

  • location (str, optional) – The location of the solution on the robot. Usually a deck location e.g., ‘1A1’.

  • solutes (list of str, optional) – A list of solute names. If set, the components will be initialized as solutes and they won’t contribute to the volume of the solution

  • sanity_check (bool, optional) – Whether to perform a sanity check on the solution.

Raises:

ValueError – If concentrations are set without specifying a component with volume. If mass fractions are set without specifying a component with mass or the total mass.
