Hi Brian, Thanks a lot for your reply. Say that I have the titration model, based on your suggestion, I can plot the minerals reacted. But in the XY plot, if I choose "minerals" as the variable type for Y, these minerals are the ones that system newly generated, right? They are the newly precipitated minerals from salt solutions after reaction, right? Please let me know your opinion. Thank you very much.

Hi Brian, Thanks a lot for your help. I can edit the thermo data now. Also, I have some other questions regarding to the "react" modeling. I put salt solutions as basis and put minerals as reactants. Is there anyway to show the mass change of reactants in the Gtplot? The minerals shown in the Gtplot is the "minerals in the system", right? And the "minerals in the system" is the newly precipitated minerals from the salt solutions after reaction, right? Please let me know your opinion. Thank you very much.

Hi there, Could you please let me know how I can edit the thermo data? It seems that I can only review the data without editing. I remember in the past with the text file I can go in to edit it. How about in GWB 10? Please let me know. Thank you very much for your help.

I am wondering whether there is anyone interested in a 3-day GWB training in North America (for example, Champaign IL). The tuition fee is $4500 but we can split the cost. Date (prefer in June, July or August) and location are flexible with me. Please contact me for details if you are interested. Thank you very much.

Hi Brian, Thank you very much for your explanation, What iss the highest ionic strength the B-dot equation (extended form of Debye-Huckel) can accomodate? If the total water loss for my system is 50%, can I still use "thermo.dat"? Thank you very much!

Hi Brian, I have modified "thermo_phrqpitz.dat" based on "thermo.dat", since I need Aluminum and Silicon to be added in the initial condition. In my calculation, I considered fluid evaporation and used "Flow-through configuration". However, after loading the modified database, the calculation gave me "Initial solution is too supersaturated". There is no further calculation. But, when I use "thermo.dat" to do the calculation, I could get a plot. Could you please let me know whether I can modify "thermo_phrqpitz.dat" and how? Or should I just use "thermo.dat" for fluid evaporation reaction path models if there is more element in my system? I have attached the script and the modified database with this post. Please let me know your opinion. Thank you very much! thermo_phrqpitz_WXM.dat Minerals-thermo.dat.rea

Hi Brian, Thank you for your reply. I will send you an email with the files. Thanks a lot for your help!

Hi Brian, Thank you very much for your reply. I really appreciate it. I have run one simulation on X2t for 5 days now and it is still calculating at the present. I am wondering usually how long is one simulation of X2t. And what affect the number of steps? It shows Step "9633000" now. Is that determined by Domain? I set the Domain as: X (3km), Y (3km), Z (1km) and both nx, ny (50). What unit is nx and ny? I put in the similar data and domain (but no Z) for X1t, it ran for only 5 min. How do I shorten the calculation time? Thank you very much! Looking forward to your reply.

Hi Brian, Thank you very much for your reply. I really appreciate it. I can include Kd value I need in .dat file and add that file through File>>sorbing surface. But I did not find the Inert varialbe from Config>>Variables menu to set the sorbing mineral mass. If I do not include any minerals in the Initial, do I have to set the mass when using X1t/X2t? Thank you very much for your great help!

Hi, I am wondering whether I can include adsorption coefficient onto the X1t or X2t. Thanks a lot!
