RE: Question about type 81 (Borehole model (Dr. P. Pahud)

["Jong, M.J.M." <jong@xxxxxx>]

Michael,

Thanks for your answer. I never runned TRNSYS in the debug mode, so can you
tell me how to to this ?

I know which parameter of type 81 is the reason of the range check error.
When I introduce symmetry groups, I get the range check error. When I have
only one borehole heat exchanger (with the same parameters), everything is
OK. So there must be something wrong with configuring the symmetry groups,
the question is what.

I also have another question. For the same project I make a simulation of 20
years (simulation end time is 175200 hour). In my model I have some
converging problems. In the *.lst file you can see the number of the
iteration call which causes this problem. When this number > 1.000.000, on
my screen appears a dialog box with a fortran error. I only have to click on
OK and my simulation goes on. The problem is that I want to simulate my
model at night and then I am not sitting behind my PC, so I cannot finish
the simulation in one night. Do you have a solution for this ?

With kind regards,

Maurice Jong.
