RETC Program

ladycares_89 · Post by **ladycares_89** » Fri Aug 17, 2012 2:59 am

I cannot run the program in this PC since it was being restricted by the admin user. Thus, I had found some that I can use Microsoft excel trough solver. Unfortunately, I find it hard since I do not know how to make it work. I am working on finding the pore size distribution index b of the Campbell (1974) model and the parameters #1138;r, á, m and n of the van Genuchten model, m=1-1/n and #1138;s=0.742 m3 m-3.
Can anyone help me how to this one using in excel?
(this are the data)
Suction Volumetric water content
h (cm H2O) #1138; (m3m-3)
1 0.742
10 0.738
30 0.713
63 0.603
100 0.526
200 0.463
1000 0.380
1995 0.367
2619 0.315
10816 0.233
12589 0.284
575510 0.101

clarification...
#1138;r is theta r
and the a next to it is alpha
#1138 = theta

RETC was designed for Windows XP and older systems and there indeed can be problems with UAC on Windows Vista, Windows 7 or newer Windows. However, there are at least two simple solutions:

1/ Run RETC "As Administrator" or use the "Compatibility mode" see http://www.sevenforums.com/tutorials/11 ... rator.html

2/ If you have Windows 7, install "Windows XP mode" (see http://windows.microsoft.com/en-US/wind ... s-xp-mode/) and run RETC there.

I was logged in as guest user that is why I cannot run the program. everytime I tried it keeps on asking the admin password.

Thank you by the way...
