T-MATS: Mixer Library Block
This block simulates the performance of a flow mixer using basic thermodynamic equations, properties, and table lookups.

Mixer Inputs:

Mixer Input	Description
GasPthChar1	Gas Path Characteristics Input 1, 5x1 vector consisting of: - W - gas path flow [pps] - ht - enthalpy [BTU/lbm] - Tt - Total Temperature [degR] - Pt - Total Pressure [psia] - FARc - Combusted Fuel to Air Ratio [frac]
GasPthChar2	Gas Path Characteristics Input 2, 5x1 vector consisting of: - W - gas path flow [pps] - ht - enthalpy [BTU/lbm] - Tt - Total Temperature [degR] - Pt - Total Pressure [psia] - FARc - Combusted Fuel to Air Ratio [frac]

Mixer Outputs:

Mixer Output	Description
GasPthCharOut	Gas Path Characteristics Output, 5x1 vector consisting of: - W - gas path flow [pps] - ht - enthalpy [BTU/lbm] - Tt - Total Temperature [degR] - Pt - Total Pressure [psia] - FARc - Combusted Fuel to Air Ratio [frac]
NErr	Normalized error

Mixer Mask Variables:

Mixer Mask Variablet	Description
Aphy1_M	Area of input 1 (in^2)
Aphy2_M	Area of input 2 (in^2)
s_M_Imp1_M	Impulse 1 scalar
s_M_Imp2_M	Impulse 2 scalar
s_M_V1_M	Velocity 1 scalar
s_M_V2_M	Velocity 2 scalar
Y_M_FARVec_M	Fuel to Air Ratio Vector (Y-axis)(cx1)
T_M_RtArray_M	Rt Array (Rt = f(FAR))(cx1)
X_M_TVec_M	Mixer Temperature Vector (X-axis for Gamma calc)(dx1)
T_M_gammaArray_M	Mixer Gamma Array (Gamma = f(Tt,FAR))(dxc)
iDesign_M	Design fork (0, 1, 2) 0 - iDes Enabled, Calculate mixer input areas based on design variables When iDesign is set to 0, Aphy1_M and Aphy2_M from the General tab will not be used. Throat areas calculated will be saved in the specified file (FVar_M). 1 - Mixer throat area variables will be overwritten (mask Initialization) with values from a specified file (FVar_M). When iDesign is set to 1, Aphy1_M and Aphy2_M from the General tab and the Design values from the iDesign tab will not be used. 2 - Mixer throat area from the General tab will be used in the nozzle module. When iDesign is set to 2, Aphy1_M and Aphy2_M from the General tab will be used; Design values and file definitions from the iDesign tab will not be used.
SWPS_M	primary flow switch ( 0 - primary flow is input 1 , 1 - primary flow is input 2
BPRDes_M	Design pressure ratio [W1/W2]
MNDes_M	Primary flow mach number
FVar_M	File name for iDes Variables
SVar_M	iDes Variable Surname
Aphy1des_M	iDes mixer input 1 throat area variable name
Aphy2des_M	iDes mixer input 2 throat area variable name

Notes: Vectors are the x and/or y axis to a table made of an array. Scalars are used to "scale" the mixer equations.
