</math>Function for calculate the exciton distribution. We usually use this equation for organic material. Behavior of exciton will follow this equation. You can see the detail in Subroutine_exciton1D.

Singlet Rate Equation: $\frac{S}{dt}=D^S{\nabla}^2{S}-(k_{r}^S+k_{nr}^S+k_{e}^Sn+k_{h}^Sp+k_{TS}T)n^S+\alpha\frac{\gamma_{TS}}{2}{T}^2+G_{S}$

Triplet Rate Equation: $\frac{T}{dt}=D^S{\nabla}^2{T}-(k_{r}^T+k_{nr}^T+k_{e}^Tn+k_{h}^Tp)T-\gamma_{TS}T^2-\frac{\gamma_{TT}}{2}{T}^2+G_{T}$

Physical Mechanics
1. Exciton Diffusion: $D^S{\nabla}^2{n_{ex}}$ 2. Exciton Quenching: $(k_{r}+k_{nr})n_{ex}$

Where　

$D$ is diffusion coefficient.
$\tau$ is relaxation time of exciton.
$\gamma$ is annihilation rate constant.
$G$ is exciton generation rate.

Parameter Explanation

n : the number of tables we usually set n as 5.
a : The type of exciton solver mode

 1: Time-dependent triplet solver 
 123: Time-dependent triplet and singlet solver (For TADF OLEDs model)
 3: Triplet Exciton Solver (For PhOLEDs model)
 6: Singlet and Triplet Exciton Solver (For TADF OLEDs model)
 4: Triplet Exciton Solver with exciton blocking boundary 
 7: Singlet-Triplet Exciton Solver (For TTF/TADF OLEDs)
 71: Time-dependent singlet-triplet exciton solver with pumping time (For TTF/TADF OLEDs)
 711: Time-dependent singlet-triplet exciton solver (For TTF/TADF's TrEL and TRPL spectrum)

b : Start time (For time-dependent solver)
c : dt (For time-dependent solver)
d : End time (For time-dependent solver)
e : savenum (For time-dependent solver)
D : diffusion coefficient. $(cm^{2}s^{-1})$
kr : radiatvie rate constant $(s^{-1})$
knr :non-radiative rate constant $(s^{-1})$
gamma : quenching coefficient. $(cm^{2}s^{-1})$
g : generation rate if you wanna let whole recombination rate change into exciton you should set g as 1.
