Glossary

case
A case is defined with an initial mesh and a list of adaptations.
error indicator
The error indicator is a field that is expressed over the elements. It represents an estimation of the error between the real solution and the computed solution.
field
A field is expressed over a mesh, onto node or element, with 1 or more components.
hypothesis
A hypothesis describes the conditions that governs the modification from a mesh to another one: refinement and/or unrefinement, etc. A hypothesis is referenced by 1 or more iterations.
iteration
An iteration is the process that transform a mesh to another one into a case. An iteration implies refinement and/or unrefinement, following the associated hypothesis.
level
The level of an element corresponds to the number of splitting that were done to obtain it. The levem of the elements in the initial mesh is 0.
MED
It is the excange format for the meshes and the fields in SALOME.
refinement
The refinement is an operation that consists in splitting the selected elements.
unrefinement
The unrefinement is an operation that consists in removing the selected elements. In fact, the objective is to cancel a previous splitting: a ‘higher’ level than the initial mesh cannot be obtained.
zone
A zone is a region that may govern the adaptation: every element with at least 2 nodes inside the zone is split or removed, depending on the choice.
