I'm trying to understand how to use the ALE Adaptive Mesh feature. I want to implement it on a simple cantilever beam with a rectangular cross section. When I run the simulation however, I get the error saying: "ADAPTIVE MESH CONSTRAINT OPTION MAY NOT BE USED IN ANALYSIS WITH LINEAR GEOMETRY." What does this mean and how can I fix the problem? What simple procedures should I follow to apply an adaptive mesh to a part? I would appreciate any help on adaptive meshes.
