3. Modeling A#
3.1. Characteristics of modeling#
The mesh is done using TRIA6 of the D_ PLAN_HM_P modeling.
The aim is to test the solution in terms of movement and pressure given by Code_Aster. We also test the computer non-regression of the calculation of the residual error indicator for permanent HM modeling.
3.2. Characteristics of the mesh#
Number of knots: 43
Number of meshes and types: 16 meshes TRIA6
The mesh is refined uniformly 1 times using HOMARD.
3.3. Tested sizes and results#

We also test the computer non-regression of the global components ESTERG1 and ESTERG2 of the error indicator. Absolute tolerance is therefore severe: \({10}^{-13}\).
