Re: View Source Code




PHREEQC 2.4.2 is embedded in PhreeqcI. PhreeqcI simply accumulates data for
an input file to PHREEQC, so the transport module is available in the
source code for PHREEQC in the file transport.c. It's gotten a little ugly,
but in outline, there is an initialization, and then a loop through the
number of time steps (shifts). For each time step, there is an advective
step and zero or more dispersive steps. If there are multiple dispersive
steps, half are performed before the advective step, and half are performed
after. There are also sections to allow diffusion into a stagnant zone and
transport of heat, which make it fairly cluttered. The file advection.c
also does transport, but is much simpler to read because it does not
include dispersion.

BTW, we just released PHREEQC 2.5 and PhreeqcI RC1, available at
https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc.

Hello

Is there a way to view the source code for the 1-D reactive transport
module of PHREEQCi alpha verson 2.4.2?

Thanks
Aaron Redman
