Immersed boundary methods have been widely used for simulating flows with complex geometries, as quality boundaryconforming grids are usually difficult to generate for complex geometries, especially, when motion and/or deformation is involved. Complex geometries can be conveniently represented using triangulated surfaces in a Lagrangian manner. A major task in immersed boundary simulations is t...
We present a general—i.e., independent of the underlying equation—egistration procedure for parameterized model order reduction. Given spatial domain $$\varOmega \subset \mathbb {R}^2$$ and manifold $$\mathcal {M}= \{ u_{\mu } : \mu \in \mathcal {P} \}$$ associated with parameter {R}^P$$ parametric field $$\mu \mapsto L^2(\varOmega )$$ , our approach takes as input set snapshots $$\{ u^k \}_{k=...
finite cell method, are employed to compute a series of benchmark problems in the finite strain von Mises or J2 theory of plasticity. The hierarchical (integrated Legendre) shape functions are used for the finite element approximation of incompressible plastic dominated deformations occurring in the finite strain plasticity of ductile metals. The computational examples include the necking under...
Researchers in bioelectromagnetics often require realistic tissue, cellular and sub-cellular geometry models for their simulations. However, biological shapes are often extremely irregular, while conventional geometrical modeling tools on the market cannot meet the demand for fast and efficient construction of irregular geometries. We have designed a free, user-friendly tool in MATLAB that comb...
