Use case for Cubic Mesh Elements


I have a FEM meshing question (independent on Calculix).

I use FEM for mechanical problems and for that purpose, I always use mesh elements with quadratic discretization. I know why I usually shouldn’t use linear elements but is there a use case for cubic elements? Maybe with hyperelastic materials? Some programs offer also 4th order mesh elements…

I wish you all a nice day. :slight_smile:

You can use hyperelastic materials even with linear elements. Take a look at this reference for h/p-refinement benefits.
