7. Summary of results

Since the simple objective of this test case is to check the non-regression, no remarks need to be made about the value of the results. The reference is that of the Code_Aster calculation on the day of the first return and must be found later.

Examining the command files, it will be noted that the loads must be done on entities with the appropriate dimension.

• a node for a punctual loading; for example a displacement imposed on a corner,

• a segment for linear loading; for example, a pressure distributed in 2D,

• a triangle for surface loading; for example, a force in 3D.

Moreover, it should be noted that these loads must be expressed on groups of nodes or meshes and not on knots or and meshes. In fact, after adapting the mesh, the groups are reconstituted. The loading command is therefore the same, regardless of the mesh.

By respecting these two loading rules, mesh adaptation is possible.
