Yes, this seems a much better solution than me adding all the components.
I really appreciate your help in this regard.

Thank you for your response. I wrote N(-3) in the component list but HP1 was unable to recognize that. Maybe, HP1 is using an older Phreeqc database.
However, I did add N(-3) as a new master species and it has been working fine.

N(-3) lacking in HP1

I am trying to incorporate a soil column with landfill minerals. I need to study redox in the system. I am unable to enter N(-3) in the list of "HP1-Components". I do see the option N(5) and N(3). I still tried to input N(-3) myself but it says that it needs to be defined. Any suggestion on why I ca...

Diederik,
The example would help a lot. I have just been reading about UCODE but an application with HP1 would be great.

HP1- Inverse modeling

I want to study the effects of infiltrating a column that has soil from a landfill site. I know the infiltrating water chemistry and outflow but I want to inversely model the redox couplings taking place in the column. Does the HP1 have any inverse modeling capabilities? or do you have a test versio...

HP1 - redox

The HP1 manual (2005) states that it can't take care of some of PHREEQC capabilities like redox reactions. Does the beta version of Hydrus/HP1 incorporate that?

DPM 2nd order in Hydrus 2d/3d

I am trying to simulate soil columns with multiple macropores. I want to compare DPM with 1st order water transfer function to DPM with 2nd order transfer function (Kohne and Mohanty, 2004). Is that capability available for use? In Hydrus 1d I just changed the options.in file to compare DPM 1st and ...
