On conforming tetrahedralisations of prismatic partitions
We present an algorithm for conform (face-to-face) subdividing prismatic partitions into tetrahedra. This algorithm can be used in the finite element calculations and analysis....

Discrete maximum principle for parabolic problems solved by prismatic finite elements
In this paper we analyze the discrete maximum principle (DMP) for a non-stationary diffusion reaction problem solved by means of prismatic finite elements and theta-method. We derive geometric conditions on the shape parame...

Finite element method on 3D mesh with layer structure -- application on flow and transport in porous media
We introduce a formulation of the finite element method (FEM) adapted to typical geometry of groundwater problems. The three-dimensional domain is discretized finite elements on trilateral prims. We show an alterna...

Formation of 0001-rotation-type kink boundary in Mg-Zn-Y alloy with long-period stacking ordered structure
The dislocation configuration around the 0001 0001 a 0001 a a slip system are numerically reproduced by a crystal plasticity finite element analysis. Geometrical softening should be significant despite kink-band formation stimulated...
