control volume method by TRNSYS

["F.ajmi" <F.Al-ajmi@xxxxxxxxxxx>]

Hi, TRNSYS users
can any body help,
a ground temperature was solved analytically using an equation which was 
developed by several Authors (i.e. Labs model). an attempt to solve the 
problem using CFD by control volume method,  (i.e. one-dimensional 
transient conduction equation).
 The numerical solution with the explicit and implicit method (Both are 
compared with measured data) was used. As we know these two method solved 
using discretisation equation for various nodes, three equations with at 
least of three unknowns were found, which may require a computer program 
for matrix solver or may be other tech. does any one solve similar problem 
using TRNSYS, any help.
Thanks in advance
