David, Can you help with answering this question? Ken ---------- Forwarded message ---------- Date: Wed, 16 May 2001 16:01:58 -0400 From: Carol Stein and Dave McTigue <mctigue@xxxxxxxxxxxxx> To: Ken Stollenwerk <kgstolle@xxxxxxxxxxxxxxxxxxx> Subject: Editing PHREEQC databases Ken ? My apologies for bugging you about this, but I am having problems editing the PHREEQC database and the User?s Manual doesn?t offer any information. Two problems that I?ve encountered: 1) I changed the equilibrium constant for Hfo_wH2AsO3 in Wateq4f and saved the edited version to a different file name, as a ?formatted text (space delimited)? file. No other format seems to run. What is the format of the original file? I noticed that the edited version is about 50% bigger. 2) When I changed the equilibrium constant back to what it was in the original version (for Hfo_wH2AsO3, the value is 5.41) and run the same input file, I get a different result than when I used the original (unedited) database?. Any ideas as to why this is happening?!? I don?t know if any of this makes any sense to you, or if you?ve encountered similar problems ? but I?d be tremendously grateful for any advice regarding editing the databases. If it's more efficient to talk about this, please suggest a date and time and I'll give you a call. Thanks so much, Carol Stein
