I am trying to run the simulation with a time step
of less than 1 hr. I am getting an Range check error from trnsys. On further
investigation I found that the error was coming from Type 56.
The simulation runs fine with a time step of 1 hr
with no errors at all.
Further the time at which the error occurred
followed a pattern.
Time step 1 min - Error in the
beginning
Time step 3 min - Error at *.05
Hr Time step 6 min - Error at *.1 Hr
Time step 9 min - Error in the
beginning
Time step 12 min - Error at *.2
Hr
Time step 15 min - Error at *.25
Hr
Where * is any hour depending on the startime of
the simulation.
e.g When the start time was 0 min, read * as
23.
Also when the error occurred in the beginning(time
step 0,9 min) the listing file had and error
" The wall timebase must be an integer multiple of
the simulation timestep'
I set the timebase to 1 in the BUIEdit's Output
window as is recommended in the manual. On debugging from type56 I found
that one source of error was due to and array related to the building schedules
getting out of bound. Particularly it was from the function
FUNCTION NPOS(TIME,NTIME,STIME)
Line 4203 of Open_TYPE56.for For the time step of 1 min and 9 min the error
occurred at the line
T_OP(IZONE)=AOPT*TBAR(IZONE)+(1-AOPT)*T_OP(IZONE)/TOTAREA
Line 9901
I have no clue about why this is
happening, can anyone please help me out with this.
Thank you,
