Dear,  
All

How can i determine batches and particle?

And can i enter the batches value with 450 and the particle value with 5000?

Thx  
Aul

Hi Aulia,

Of course you can run your simulation with 450 batches and 5000 particles.

How can i determine batches and particle? \>\> Source convergence [Shannon Entropy]. Take a look Source convergence example.
