[TRNSYS-users] Dum Problems with online plotter

Dear Carlos Flores,

I believe this is actually a bug with the adding an extra online plotter.
I don't exactly know what the root cause of the problem is, but I believe
it has something to do with the *.pti file and TRNEXE.  In the mean time
to avoid this bug, please try deleting your project's *.pti file in your
project's directory and then run the simulation.

Best regards,

Matt Duffy

Subject:[TRNSYS-users] Dum Problems with online plotter


Hello all,

I modified a STEC library fortran source code and created a new proforma for
one kind of Solar collectors. After debugginf for a while I was finally
getting good results as the proforma was doing exactly what I wanted.

So what's the problem?

If I use only a printer I get good results, all the variables give results
that would sound quite reasonable and no "NaN" nor "infinite" values are in
the final results. Now --this is the dummy-part-- if I add an online plotter
to the project (in order to see things better) I get this "floating point"
error right at the beggining (at the second time-step... 1hr). It doesn't
matter what do I connect the online plotter with... If I connect it to a
forcing function (for example), which doesn't really interact with my
created Type it does the same thing!!!

I tried debugging my TypeXXX.for, but when I'm on it I get to the TRNSYS.for
file and that's where the problem occurs. This happens almost at the end of
the TRNSYS.for file, when the time-step it's about to conclude (after this
loop, line 959):

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
C    SEND THE ONLINE PLOTTER PARAMETERS AND OUTPUTS BACK TO THE EXECUTABLE
FOR PLOTTING
      DO J=1,5
        DO I=1,20
           PLOTOUT(I+(20*(J-1)))=PLOUT(I,J)
        ENDDO

        DO I=6,20
           PAROUT(I+(20*(J-1)))=PROUT(I-5,J)
        ENDDO
      ENDDO

C    AT THIS POINT THE SIMULATION IS FINISHED AT THE CURRENT TIMESTEP
      RETURN
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After this (and BEFORE the error) it jumps to the end of the file (where it
says "END"), and then I get the following error in Visual Studio:

"No symbols are loaded for any call stack frame. The source code cannot be
displayed". I click next and I get the error in TRNSYS.

Has anyone had this error before? I'm doing the simulations for my master
tesis and I haven't been able to find out how to fix it.

Thanks to all

Carlos
