Dien Li Posted March 10, 2015 Share Posted March 10, 2015 Hi, Brian How are you! I am trying to practice a modeling using X1T. The modeling is on weathering of soils, the data were given on page 410-420 of Craig's book (2008). My question is how to set up the entrance data for kailonite, gibbsite and tridymite, specially how to deal with the nucleus = 4000. Attached please see the data file I am trying to work, could you please help looking at it. Thanks. Dien Quote Link to comment Share on other sites More sharing options...
Dien Li Posted March 11, 2015 Author Share Posted March 11, 2015 Hi, Brian I tried to simply use COMMAND to input all data and information from your text book (Bethke 2008, page 410). I used thermo.dat. It looked that I could run the model, but the results for kaolinite and gibbsite were different from your text book Fig. 27.3 for the first 0.1 meter profile, after that, it looked all identical. I attached the new input file. Could you instruct? what datebase you used to get your texk book results. Thanks.

Brian Farrell Posted March 11, 2015 Share Posted March 11, 2015 Hi Dien, It looks like the concentration of Al+++ in the inlet fluid is too high by a factor of 1000. The textbook has Al+++ at 1 ug/kg, not 1 mg/kg. Once I change that value my results seem to match those in the textbook.

Dien Li Posted March 11, 2015 Author Share Posted March 11, 2015 Hi, Brian Thanks. I noticed that the Al+++ issue in the first run. Anyhow, I now found it out. Thanks indeed. Dien Quote Link to comment Share on other sites More sharing options...
