non‐conforming meshesconstraintsA methodology to connect two or more non-conforming meshes generated from a geometric model is presented. The problem leads to a variational problem subject to constraints. The emphasis of the work is on constraints construction. Two methods, namely, discrete connection...
High-order finite elements constructed over these curved triangles achieve optimal accuracy, which has customarily proven difficult in numerical schemes that adopt nonconforming meshes.Aside from serving as a quick and simple tool for meshing planar curved domains with complex shapes, the method ...

- Added support for pyramids in non-conforming meshes. Currently only isotropic refinement is supported in this case. - Removed the support for the Mesquite toolkit. We recommend using MFEM's TMOP functionality instead for mesh optimization. See the mesh-optimizer miniapp. - Added a fast ...

non-conforming mesheslocal time-steppingIn this paper we present various numerical methods for solving time-dependent fluid-structure interaction problem in two or three dimensions that we claim to be efficient, robust and highly accurate. These methods, based on mixed variational formulations, are ...
The ability to handle non-conforming meshes is essential for isogeometric finite element systems to avoid manipulations of the geometry model. In general two possible strategies exist. The first one is to enhance the weak form of the potential with additional terms to constrain the deformations of ...
