For a stripping solution I wouldn't recommend just HCl because as kenvlach stated HCl will pit a metal. Chlorides are some of the worst pitting ions. The reason is that they are relatively small and their diffusion is fast thus help keeping the pitted regions neutral. Also, the chlorides are...

"Brick elements yield better stress results in contact analyses" Why is that? I would think that two coincident and lined up (node for node) tet10 meshes would model contact well.

Actually cold work can affect the elastic properties of a material. This effect is called texturing because the grains after cold work are aligned (not perfectly aligned) along the direction of material flow. This tends to give some anisotropy in material properties. Regards MMATguy

Hello, I think analysts in industry tend to shy away from using quadratic tetrahedrals and advocate meshing the whole model with bricks even if it takes 2+ weeks. As far as accuracy goes Comparing the shape functions, quadratic tetrahedral elements are just as (or more) accurate as a linear...
