Detailed Description

Types and routines that collectively implement a basic ECLIPSE-style equilibration-based initialisation scheme.

This namespace is intentionally nested to avoid name clashes with other parts of OPM.

Function Documentation

template<class Grid , class CellRangeType >

std::vector<double> Opm::Equil::computeRs	(	const Grid &	grid,
		const CellRangeType &	cells,
		const std::vector< double >	oil_pressure,
		const std::vector< double > &	temperature,
		const Miscibility::RsFunction &	rs_func,
		const std::vector< double >	gas_saturation
	)

Compute initial Rs values.

Template Parameters

CellRangeType

Type of cell range that demarcates the cells pertaining to the current equilibration region. Must implement methods begin() and end() to bound the range as well as provide an inner type, const_iterator, to traverse the range.

Parameters

[in]	grid	Grid.
[in]	cells	Range that spans the cells of the current equilibration region.
[in]	oil_pressure	Oil pressure for each cell in range.
[in]	temperature	Temperature for each cell in range.
[in]	rs_func	Rs as function of pressure and depth.

Returns

Rs values, one for each cell in the 'cells' range.

bool Opm::Equil::isConstPc ( const BlackoilPropertiesInterface &  props, const int  phase, const int  cell  )
