Abstract
To control the numerical quality of non-linear simulations
allows to automate the choice of discretisation. Within the
framework of time dependent problems, this quality depends
on the error made in the calculation of the transformation
history. Generally, before obtaining a calculation of a
satisfactory quality, it is necessary to carry out an evaluation
on the numerical approximations to use by exploiting all the
history of approximate solution defaults. We propose a
strategy which naturally includes this expert stage. The
desired solution is built iteratively, bettering all the history
at each iteration thanks to the LATIN method. A global error
estimator is provided by the dissipation error. To pilote the
adaptive computation, we propose a partition of this
estimator in indicator associated to each kind of error
contribution.
