Having 5 transversal angles [0°, 20°, 50°, 70°,
90°] and 3 longitudinal angles [0°, 50°, 90°] my file .dat is something
like this (I don't write all 15 values of the column):
0 20 50 70 90
0 50 90
1
0.95

In Type538 I set parameter 11 (Number of transverse
angles) to 5 and parameter 12 (Number of longitudinal angles) to 3.
Now, I tried to run the simulation: Trnsys didn't work: it said that
there was an error without specifing details:
Fatal Error at time : 3245.010000
Generated by Unit : 3
Generated by Type : 538
TRNSYS Message 109 : Error reading data stored in logical unit.
NOTE: the reported logical unit number may be automatically or
internally ASSIGNed, or you may have specified the incorrect number of
independent variables.
Reported information : Logical Unit number 33
So I tried to change parameter 11 and parameter 12:
I set parameter 11 to 3 and parameter 12 to 5 (I simply reversed the
number of transversal angles with the number of longitudinal angles).
In this way the simulation ran!
So the question is this: the file .dat has to be
written as described in the manual, and there is only an inversion in
the definitions of "parameter 11" and "parameter 12", so that the only
change to do is the one described above?
Or the definitions of "parameter 11" and "parameter
12" are right and there is to change the file .dat putting in the first
line the longitudinal angles and in the second line the transversal
angles? In this case, the column with all the possible multiplications
is to be left as it is described in the manual, or I have to modify it
in this way:
<IAM 1 1> IAM for long. angle 1, transv. angle 1
<IAM 1 2> IAM for long. Angle 1, transv. angle 2
...
<IAM 1 Nl> IAM for long. angle 1, transv. angle
Nl
<IAM 2 1> IAM for long. angle 2, transv. angle 1
<IAM 2 2> IAM for long. angle 2, transv. angle 2
...
<IAM 2 Nl> IAM for long. angle 2, transv. angle
Nl
<IAM 3 1> IAM for long. angle 3, transv. angle 1
...
<IAM Nt Nl> IAM for long. angle Nt, transv. angle Nl
?
I hope I've been clear enough, thank you all,
