[TRNSYS-users] Problem of convergence

[Jeff Thornton]

<I have a problem of convergence . I modified convergence parameters in
control card, but there is one error and I don't know why.>

Well you don't seem to have a problem with e-mail convergence - I got all
three (so far) of your identical messages.  With 20 or so e-mails this
past week you may want to consider the focus of this e-mail list.  The
list is designed to provide users with a resource to answer TRNSYS
questions, get information on latest updates and upgrades, interface with
the developers and other users around the world.  Yes it is designed to
help users with TRNSYS problems - but it is not intended to replace common
sense, trying a few things, checking other examples and reading the
documentation.  This should not be the first thing you do (e-mail) right
after you get a warning - take a moment and try and understand the content
of the warning and ways you can resolve it.  Then if you get stuck - email
the list.

At this point I think you should take a step back from your project and
spend some time reading the TRNSYS getting started manual, study some of
the examples, and try and figure out the best way to apprach the
simulation problem you are trying to solve.  Maybe take a training course?
 Then start your project by dragging out a component, setting the
parameters and then "drive" the model with a few represenative inputs. 
Connect it to a Type 65 plotter and make sure you understand how the model
is responding.  Then drag out the next component, connect it to the first
component and make sure that combination is behaving as you expect it
to....  Many times users will drag out 100 components, connect them up and
wonder why it doesn't work right away - and its almost always because they
missed something.

Just a bit of advice from a long time user.  Good luck with your simulations.
