Detailed Description

Apply piecewise linear differentiation (i.e., compute slopes) on a set of dependent variables in a linearised output table.

Function Documentation

void Opm::DifferentiateOutputTable::calcSlopes	(	const std::size_t	numDependent,
		const Descriptor &	desc,
		LinearisedOutputTable &	table )

Apply piecewise linear differentiation (i.e., compute slopes) on a set of dependent variables in a linearised output table.

Assumes that the independent variable is stored in the first column (column ID zero).

Parameters

[in]	numDependent	Number of dependent variables. Usually one or two. Dependent variables are assumed to be stored in columns one through `numDependent`.
[in]	desc	Columnar data differentantiation table request. Must refer to a particular sub-table of the linearised output table.
[in,out]	table	Linearised output table. On input, column zero contains the independent variable in each of sub-tables and columns one through `numDependent` contain the dependent variables. On output, columns through contain the slopes of the dependent variables.

In partcular, column

for

contains the derivatives of column j with respect to column zero. We define the slopes as

for all

(in table k).
