The TOLERANCES statement is a control statement used to specify
the error tolerances to be used during a TRNSYS simulation. The statement
has the form:<br><br>
TOLERANCES eD eA<br>
or<br>
TOLERANCES -zD -zA<br><br>
where<br><br>
eD<x-tab> </x-tab>is a relative (and
zD is an absolute) error tolerance controlling the integration
error.<br>
eA<x-tab> </x-tab>is a relative (and
zA is an absolute) error tolerance controlling the convergence of input
and output variables.<br><br>
Example:<x-tab> </x-tab>
The error tolerances eD and eA are both to be set to one-tenth of one
percent. The TOLERANCES statement is then<br><br>
TOLERANCES .001 .001<br><br>
The tolerances for the new equation solver (SOLVER=1) are considered
differently. The mean standard deviation for all of the equations
is calculated and must be less than the specified tolerances to reach
convergence.<br>

I would like to know the definition of the "Tolerance
Convergence" in Global Infos. Because I loss the TRNSYS manual
(Volume I). Is it a percentage no?<br>
When I changed this value from 0.001(define) to 0.4, my data output has a
lot of difference.<br>
<br>
Thanks.<br>
