The TRNDll is the compiled TRNSYS code; there is nothing that can be
looked at in it. IISiBat is the Trnsys15 name of the graphical
interface. <br>
<br>
If you are receiving only a few warnings during your simulation
about convergence problems then I would not worry about them. If you
are receiving a lot of non convergence warnings then you need to
determine the cause of them. If enough warnings are produced then
the simulation will end with an error.<br>
<br>
The two most common problems leading to nonconvergence are time
steps that are too long and/or insufficient thermal capacitance in
the system. Your time step should probably be on the order of 5
minutes and you should make sure that you are modeling sufficient
piping and thermal storage tanks so that none of the pumps in your
system can pump more liquid through a loop in one time step than can
be stored in the loop.<br>
Kind regards,<br>
