The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is computed and compared to a reference value.

By using elongated mesh elements the total mesh size can be reduced resulting in significantly faster simulations (especially for full 3D simulations).
Unfortunately, most automatic mesh generation algorithms try to avoid anisotropic mesh elements, so if the geometry allows for it, the best way to generating such anisotropic meshes is by manually generating structured meshes.Electro-Osmotic Flowhttps://www.featool.com/model-showcase/06_Multiphysics_10_electroosmotic_flow1/Thu, 22 Jul 2021 00:00:00 +0000https://www.featool.com/model-showcase/06_Multiphysics_10_electroosmotic_flow1/This multiphysics example examines microfluidic flow and coupled mass transport due to electroosmosis in a channel with a T-shaped junction. With application of an electric field in a micro channel a flow effect is induced along the walls due to chemical reactions between the liquid and the wall material. This effect is called electro-osmotic flow (EOF), and can for example be used in chemical analysis to separate reactants and chemical species.
