Hi
I am simulate the TCE transport case via phreeqc
I want to simulate the case that:
1. the velocity varied with each cells
2. Concentration varied time in one constant observe point(cell)
I already read the example and manual
However, I still don't know how to do that with phreeqc
Anyone can help me?
thank you

The PHREEQC scripts for all of the examples are provided in the manual and the distributions. Start with one of the examples and modify. I won't help you until you have tried something.
Advective time step is the same for all cells, so velocity for a cell depends on cell length.

Thanks for dlparkhurst:
I had tried all examples, and I know that the velocity in PhreeQC is a constant for all cell.
However, my case needs to vary velocity for each cell.
I found that those examples could not help me, so I am looking for any solution can solve this problem.

I did not say the velocity was the same for all cells. I said the time step is the same. The velocity is the cell length divided by the time step, so a longer cell has a higher velocity.
You need to provide a script before I will help you further.
