[TRNSYS-users] ...small time step problem [2]
I did some further investigation on this problems and I found out that
the problem occurred when the type 16 with smoothing option is used.
(type 16h)
The error is "Range Check Error" and happened when the subroutine CURVE
is called in the type 16. Thus I suspect that some array size might be
set too small for my time step (0.1 minute time interval) to calculating
the radiation data. CURVE subroutine is only called when the smoothing
option is choose and it calculates the radiation level based on fitting
the data with the polynomial equation.
And I think if the size of some (problem parameters) can be changed this
problem can be solved.
Are there any suggestions for that?

Subject: [TRNSYS-users] small time step problem
Dear TRNSYS user,
I have a problem when I run TRNSYS with type 16 radiation processor
component using a very small time step (0.1 minute).
Without type 16 I can run TRNSYS (based on 0.1 minute time interval)
with
no problem.
I knew that TRNSYS 16 does not have this problem anymore.
But unfortunately I am still in version 15 and my work requires a very
small time step (0.1-0.5 minutes).
Are there any hints?
Cheers,
Louis
