Adaptive linear static analysis. Multiple loading cases are not
supported. Due to linearity of a problem, the complete reanalysis from
the beginning is done after adaptive remeshing.
After first step the error is estimated, information about required density is generated
(using mesher interface) and solution terminates. If the error
criteria is not satisfied, then the new mesh
and corresponding input file is generated and new analysis should be
performed until the error is acceptable.
Currently, the available error estimator for linear problems is
Zienkiewicz-Zhu. Please note, that adaptive framework requires
specific functionality provided by elements and material models. For
details, see element and material model manuals.
Parameter nsteps indicates the number of loading cases.
Should be set to 1.
The sparselinsolverparams parameter describes the sparse
linear solver attributes and is explained in section 5.1.
The meshpackage parameter selects the mesh package interface,
which is used to generate information about required mesh density for
new remeshing. The supported interfaces are explained in section
5.6. By default, the T3d interface is used.
The errorerestimatorparams parameter contains the parameters
of Zienkiewicz Zhu Error Estimator. These are described in section 5.4.
