</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:
<math>\frac{dn_{ex}^S}{dt}=D^S{\nabla}^2{n_{ex}^S(r)}</math>
Triplet Rate Equation:
<math>\frac{dn_{ex}}{dt}=D{\nabla}^2{n_{ex}(r)}-\frac{n_{ex}(r)}{\tau}-\gamma{n_{ex}(r)}^2+G</math>


Where　
* <math>D</math> is diffusion coefficient.
* <math>\tau</math> is relaxation time of exciton.
* <math>\gamma</math> is annihilation rate constant.
* <math>G</math> is exciton generation rate.

  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 
* 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. <math>(cm^{2}s^{-1})</math>
* kr : radiatvie rate constant   <math>(s^{-1})</math>
* knr :non-radiative rate constant  <math>(s^{-1})</math>
* gamma : quenching coefficient.  <math>(cm^{2}s^{-1})</math>
* g : generation rate if you wanna let whole recombination rate change into exciton you should set g as 1.
