[TRNSYS-users] Error in Macro

[David BRADLEY]

Dr Abdunnabi,
   As Matt mentioned, if all of your collectors are plumbed in a pattern 
(say 30 in parallel or 15 in parallel and 2 sets in series) then you can 
use the "number in series" and "number in parallel" parameters to 
simulate the whole collector array with a single instance of the 
collector component. This method neglects the thermal losses from the 
piping between collectors and can't be used if you have a complicated 
flow pattern. The fewer components in your system, the faster TRNSYS 
will be able to solve them so if you can reduce the number of 
components, you will get some benefits from that.

   My guess is that when you run the smaller parts of your system (the 
micros) individually, the simulation converges well but that when you 
add the others, some output is not converging. If turning on the "debug" 
switch in the simulation control cards does not help then please send 
your input file to your distributor and they should be able to help further.
Kind regards,
  David
