twModMeta-package: twModMeta

In twModMeta: Support for array based state variables in ODE.

Description

ODE-States consisting of several elements/isotopes.

Details

This package supports the use of array based state variables with package deSolve.

This often occurs when several isotopes of the same element need to be calculated. The matrix of elements in rows and isotopes in columns, is converted to state vector with entries named: row_col

An example modMetaICBMDemo with the simple ICBM carbon turnover model is provided using radiocarbon data.

Basic meta-information structure and helper functions includes

• setting up a structure about the models Metadata twCreateModMeta

• adding auxiliary outputs to the Metadata, twSetModMetaAuxGroups

• initializing the state, initStateModMeta

• converting state vector to state matrix, twStateMatODERes

• constructing entry names twModElementNames

Data

• radiocarbon constants: c14Constants

• radiocarbon atmospheric record of the bomb peak: delta14Catm and function fmAtmosphere.
