[TRNSYS-users] trnsys message 198,441 + project

[David BRADLEY]

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.

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.

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.
Kind regards,
  David
