pkSetSpecies

Name

pkSetSpecies -- Sets the values of chemical species properties

Description

The subroutine pkSetSpecies allows setting the value of the initial concentration for one species or the values of this property for a sequence of species.

Syntax

pkSetSpecies( Property, Value, SpeciesN [, STAT] )

NameDescriptionData type and attributes
PropertyCase sensitive name of propertyCHARACTER(len=*), INTENT(IN)

{Value | Value(:)}

Values(s) of propertyREAL(double), INTENT(OUT)
SpeciesN

{Index of Species | starting index of Species}

INTEGER, INTENT(IN)
STATExecution status indicatorINTEGER, OPTIONAL, INTENT(OUT)

Results

STAT = 0: no errors; STAT = n: error number.

Comments

The only property that can be set is the initial_conc.

The Value argument sets the value of the property inquired and can be a scalar or an array. In the last case the values set are SIZE(Value) consecutive values of property.

Examples

Example E-19. pkSetSpecies: Modifying the value of the 'initial_conc' property.

When the electron energy and vibrational distribution functions are self-consistently obtained by the solution of the electron Boltzmann equation coupled to the system of rate balance equations for the vibrational levels, it is necessary to update the concentrations of vibrational levels obtained from the rate balance equations. This can be done by imposing new values for the initial_conc property.
