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.
