Struct StateBuilder 

pub struct StateBuilder<'a, E, const IG: bool> { /* private fields */ }

A simple tool to construct States with arbitrary input parameters.

Examples

// Create a state for given T,V,N
let eos = &PengRobinson::new(PengRobinsonParameters::new_simple(&[369.8], &[41.9 * 1e5], &[0.15], &[15.0])?);
let state = StateBuilder::new(&eos)
                .temperature(300.0 * KELVIN)
                .volume(12.5 * METER.powi::<P3>())
                .moles(&(dvector![2.5] * MOL))
                .build()?;
assert_eq!(state.density, 0.2 * MOL / METER.powi::<P3>());

// For a pure component, the composition does not need to be specified.
let eos = &PengRobinson::new(PengRobinsonParameters::new_simple(&[369.8], &[41.9 * 1e5], &[0.15], &[15.0])?);
let state = StateBuilder::new(&eos)
                .temperature(300.0 * KELVIN)
                .volume(12.5 * METER.powi::<P3>())
                .total_moles(2.5 * MOL)
                .build()?;
assert_eq!(state.density, 0.2 * MOL / METER.powi::<P3>());

// The state can be constructed without providing any extensive property.
let eos = &PengRobinson::new(
    PengRobinsonParameters::new_simple(
        &[369.8, 305.4],
        &[41.9 * 1e5, 48.2 * 1e5],
        &[0.15, 0.10],
        &[15.0, 30.0]
    )?
);
let state = StateBuilder::new(&eos)
                .temperature(300.0 * KELVIN)
                .partial_density(&(dvector![0.2, 0.6] * MOL / METER.powi::<P3>()))
                .build()?;
assert_relative_eq!(state.molefracs, dvector![0.25, 0.75]);
assert_relative_eq!(state.density, 0.8 * MOL / METER.powi::<P3>());
