$solvetimestep2D is a command for solving the transient behavior of the device. The format is 

$solvetimestep2D
number_of_different_steps(Nt)
steptype contact_type \delta t ~~   t_{total} par1 par2 par3 par4 ....    
steptype contact_type \delta t ~~   t_{total} par1 par2 par3 par4 ....    
...
steptype contact_type \delta t ~~   t_{total} par1 par2 par3 par4 ....    repeat Nt times


The number of parameters depeding on step type. Now we have 3 step types 

Steptype  = 1:  

\delta t,~~ t_{total},~~ vg_0 

 vg=vg_end for t<0, for t>0, vg= vg_0  


Steptype  = 2:  

\delta t,~~ t_{total},~~ vg_0 ,~~ A_{0} ,~~ \omega,~~ c_{0} 

 vg=vg_0 +  A_{0} \times sin\left( 2\pi \omega t + c_0 \right) 


Steptype  = 3:  

\delta t, ~~t_{total},~~ vg_0 ,~~  A_{0} ,~~ \omega ,~~ c_{0}  

 vg=vg_0 +  int(A_{0} \times sin\left( 2\pi \omega t + c_0 \right))

Steptype  = 4:  

\delta t,~~ t_{total},~~ vg_0 

vg=vg_end for t<0, for t>0, vg= vg_0   , generation = system generation at t<0 and generation =0 for t> 0 
 

Steptype  = 5:  

\delta t,~~ t_{total},~~ vg_0 

vg=vg_end for t<0, for t>0, vg= vg_0   , generation = system generation at t<0 and generation =0 for t> 0


For example: 

$solvetimestep2D
2
2 2 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 
2 4 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 
  vg=3.0 + 0.1 \times sin\left( 2\pi \times 10^{6} t  \right) 

  vd=3.0 + 0.1 \times sin\left( 2\pi \times 10^{6} t  \right)
