Re: [TRNSYS-users] Silly error with Calculator

Dear David,

I'll give you a couple more details, so perhaps you can tell me what can I do to get rid of this problem.

1) Originally it was the type 396 (parabolic trough component, in the STEc library).  Then, I changed the order of the components and now I get the same problem but in a different component (storage tank, type 60)

2) This only happens when I add more equations in a calculator.  If I simplify the calculations, then I don't get the error, but if I add a couple more of very simple equations I get this error.

It's 100% related with the equations I put in the calculator, but I cannot understand why. Any idea? One more thing, I have 6 calculators operating in the systems, and lots of componentes as well, can it be related with too many components for just one simulation?

Thanks again, 

Carlos

Carlos,
 The cause of that problem is an error in one of the components in the system (not in the equation calculators). Essentially, each Type in the simulation reserves space for itself in a global array of output variables. TRNSYS checks to make sure that none of the components reserve themselves 10 spaces but then write into the 11th space (as an example). One of the components in your simulation is writing outside its allowed space. The *.lst and *.log files should indicate which Type is to blame. If it is one of the standard Types, I can fix it. If it is one of the STEC components, please let me know that as well but also bring it to the attention of the STEC library developers.
Kind regards,
 David

Dear colleagues,

I'm modelling a solar power plant, using several components from the STEC library, including the Parabolic Trough field model (396).  I've been using several calculators to include some heat losses that were not included in some components.

So far, I've been using 5 different calculators in my model, and with the last calculation I got the following error:
---------------------------------------------------------------------------------------------------------------------------------------------
TRNSYS Message    427 : An OUTPUT from the specified component model has been written to the global OUT array in a location beyond the allocated number of outputs from this model. Please check the component carefully to insure that INFO(6) is set correctly. The simulation has been aborted to avoid problems caused by over-writing the outputs from other component models
---------------------------------------------------------------------------------------------------------------------------------------------

This error is launched by the Parabolic Trough model, and I don't understand what really means and what could I do to repair it.  The calculations are really simple, and I don't see how could it be any problem with them.  Does anybody knows what causes this problem?
