This field sets the maximum number of iterations allowed in the
iterative solver. We remind that for the
time being, the solver used in SYRTHES
is based on a preconditionned conjugate gradient.
It is therefore a positive integer. The greater the number
the more costly the calculation if precision has not been reached before.
By default, the limit has been set to
100, which is generally a good tradeoff between precision and cost.
<p>
In fact, to drive a calculation, user can play with two parameters:
<ul>
<li> the solver precision </li>
<li> the maximum number of iterations in the solver<li>
</ul>
When analysing a previous run in the listing, in case of poor convergence,
user may increase the maximum number of iteration allowed.
An alternative, to improve convergence rate
can be to reduce the time step used.
