Set tstep (the time (in h) per iteration) with different values does not change the simulation results.

Hi @jotech ,

I just find out that the simulation results from my BacArena system are the same with different values of tstep, i.e. the time (in h) per iteration.
What I did is

1. initialize the system:
   arena <- BacArena::Arena(n=100, m=100, stir=TRUE, Lx=0.025, Ly=0.025, tstep=stephours)
2. set modles:
   bac <- BacArena::Bac(model=Bsubtilis, deathrate=0.05, minweight=0.05, growtype="exponential", limit_growth=TRUE, lyse=TRUE)
   arena <- BacArena::addOrg(arena, bac, amount=500)
3. simulate the system for 5 iterations:
   sim <- BacArena::simEnv(arena, time=5)

I tried to set stephours=0.5, 1, 2, 4. However, the simulation results are almost the same.

Did you know the reason? Thanks!

Best,
Xuejian
