Full name:	Initiate a branch of the adaptive interpolation scheme.
Purpose:	Initiates a branch of the interpolation scheme with a set of conditions, phases and values to be interpolated.
Comments:	The size of the arrays IDEPEL, XMIN and XMAX are defined as the number of all components supplied by TQGNC must be provided in the same order as supplied by TQGCOM.Composition conditions are set as the normalized number of moles for each component (N(c) =value).The size of the arrays IPHSTA and PHAMNT are defined as the number of all phases supplied by TQGNP must be provided in the same order as supplied by TQGPN.The allocation of memory to each branch is performed at the first time values are retrieved using TQIPS_GET_VALUE, therefore some considerations must be made when using several branches in order to allocate the same amount of memory to each branch.
Arguments
Name	Type	Value set on call or returned
TISCOND	Logical	Set to TRUE if temperature is a condition in this branch.
TISCNST	Logical	Set to TRUE if temperature is constant in this branch.
PISCOND	Logical	Set to TRUE if pressure is a condition in this branch.
PISCNST	Logical	Set to TRUE if pressure is constant in this branch.
IDEPEL	Logical array	Set to TRUE for each element for which conditions are present.
IDISCRT	Integer	Indicates the type of discretization where: 1=linear2=logarithmic
NSTEP	Integer	Set to the logarithm (10 base) number of steps to be used to interpolate in the temperature / pressure / composition space.
IPHSTA	Integer array	Set to the status for the phases in this branch, where: 1=ENTERED, 2=SUSPENDED, 3=DORMANT, 4=FIXED
T	Double precision	Set to temperature if temperature is a condition, otherwise used as starting value.
TMIN	Double precision	Set to lower limit of temperature range.
TMAX	Double precision	Set to upper limit of temperature range.
P	Double precision	Set to pressure if pressure is a condition, otherwise used as starting value.
PMIN	Double precision	Set to lower limit of pressure range.
PMAX	Double Precision	Set to upper limit of pressure range.
RMEMFR	Double precision	Set to the fraction of the amount of free physical memory to be allocated to the interpolation scheme for this branch (value < 1.0). If a value larger than 1.0 if set, it is interpreted as the number of megabytes allocated to the branch.
PHAMNT	Double precision array	Set to the amount of the phase if defined as a fixed phase with IPHSTA.
XMIN	Double precision array	Set to the lower limit of the composition range of each component.
XMAX	Double precision array	Set to the upper limit of the composition range of each component.
IBRANCH	Integer	Set to branch number for which the variable in STRING is to be interpolated.
IERR	Integer	Returns error code.
IWSG	Integer array	Workspace.
IWSE	Integer array	Workspace
