Feature tested

The *ADAPTIVE MESH option is tested in ABAQUS/Standard for solid elements that can be part of an adaptive mesh domain.

Problem description

The verification problems that test the *ADAPTIVE MESH option are either slender beam-like structures that are loaded by gravity parallel to the length or cubical structures indented by a rigid punch.

The verification problems also test user subroutine UMESHMOTION, which provides user-prescribed mesh motion.

Results and discussion

The verification of the adaptive mesh capability is done by comparing the results of the problems with and without adaptive mesh options.

The verification of user subroutine UMESHMOTION consists of checking the nodal output to ensure correct application of the user-prescribed mesh motion.
