feos.bubble_point_pressure_derivatives¶
- feos.bubble_point_pressure_derivatives(model, parameter_names, parameters, input)¶
Calculate bubble point pressures of binary mixtures and derivatives w.r.t. model parameters.
- Parameters:
model (EquationOfStateAD) – The equation of state to use.
parameter_names (List[string]) – The name of the parameters for which derivatives are calculated.
parameters (np.ndarray[float]) – The parameters for every data point.
input (np.ndarray[float]) – The temperature (in K), composition of the first component, and an initial guess for the pressure (in Pa) for every data point.
- Returns:
(np.ndarray[float], np.ndarray[float], np.ndarray[bool])
- Return type:
The bubble point pressures (in Pa), gradients, and convergence status.
