ALE (Arbitrary Lagrangian-Eulerian) mesh adaptivity in ABAQUS/Standard
I'm doing some numerical analysis on penetration of infra-strucutres on soils (such as CPT tests) in ABAQUS/CAE .. what I'm recently challenging with is to overcome the element excessive distorsion due to large deformations... I have to apply contact constraints in my model...I would appreciate it if you share your expriences with me regarding the following tips:
1- Is it possible to use the ALE (Arbitrary Lagrangian-Eulerian) mesh adaptivity in ABAQUS/Standard? If yes, do you know of any accessible examples (.cae files) or references?
2- One strange thing is that I can run my model in ABAQUS/Standard with reports of excessive mesh distorion in 4-10 elements and still get the answer. How much I can rely on such results?
3- Are there any available examples of apllication of ALE mesh adaptivity verifying its applicability in ABAQUS?
Any help would throroughly be appreciated...
