[TRNSYS-users] Type31: Capacity of pipe - timestep of simulation

[Nikos Androulakis]

Hi all,

In a simulation of a closed loop system comprised of two pipes (type31 
or type709), a solar collector and a pump, with constant flow rate and 
known (and unchangeable) length of pipes, is the time step of the 
simulation the only changeable parameter, so as not to have convergence 
problems, warnings or other problems? In this simulation there is a mass 
flow rate such that the time step is equal to 60 seconds, so the 
calculations for the completion of the simulation are time consuming. I 
am using trnsys 16.
Thank you in advance.

Nick Androulakis.
