How to install and use phreeqcRM and the difference between phreeqcRM and the Tr

[chaoyu]

Dear seniors, I am a beginner in phreeqc, currently I want to make 1D  reactive transport model, I don't know whether I should use phreeqcRM or directly use Transport. if phreeqcRM then how this module should be installed and used, please give me an advice. Thanks

You should use the TRANSPORT capabilities of PHREEQC. You cannot use PhreeqcRM unless you couple it to a separate multicomponent transport model. I think PHREEQC should have all the capabilities you need to get started with 1D transport modeling.

Thanks for the advice, I'm now getting ready to use the TRANSPORT module for my simulation.
