MFEM Tutorials (3) Simple Linear Elasticity Problem Describing a Multi-Material Cantilever Beam Part B
Define a finite element space on the mesh. Here we use vector finite elements, i.e. dim copies of a scalar finite element space. The vector dimension is specified by the last argument of the FiniteElementSpace constructor. For NURBS meshes, we use the (degree elevated) NURBS space associated with the mesh nodes. This code sets up…

MFEM Tutorials (3) Simple Linear Elasticity Problem Describing a Multi-Material Cantilever Beam Part A
Description This example code solves a simple linear elasticity problem describing a multi-material cantilever beam. Specifically, we approximate the weak form of where is the stress tensor corresponding to displacement field $\textit{\textbf{u}}$, and lambda and mu // are the material Lame constants. The boundary conditions are $\textit{\textbf{u}}=0$ on the fixed part of the boundary with…
