SoftIGA: soft isogeometric analysis

Quanling Deng, Pouria Behnoudfar, Victor M. Calo

We extend the softFEM idea to isogeometric analysis (IGA) to reduce the stiffness (consequently, the condition numbers) of the IGA discretized problem. We refer to the resulting ap…

An automatic-adaptivity stabilized finite element method via residual minimization for heterogeneous, anisotropic advection-diffusion-reaction problems

Roberto J. Cier, Sergio Rojas, Victor M. Calo

In this paper, we describe a stable finite element formulation for advection-diffusion-reaction problems that allows for robust automatic adaptive strategies to be easily implement…

A boundary penalization technique to remove outliers from isogeometric analysis on tensor-product meshes

Quanling Deng, Victor Calo

We introduce a boundary penalization technique to improve the spectral approximation of isogeometric analysis (IGA). The technique removes the outliers appearing in the high-freque…

Automatic Variationally Stable Analysis for Finite Element Computations: Transient Convection-Diffusion Problems

Eirik Valseth, Pouria Behnoudfar, Clint Dawson +1

We establish stable finite element (FE) approximations of convection-diffusion initial boundary value problems using the automatic variationally stable finite element (AVS-FE) meth…

A fully-coupled framework for solving Cahn-Hilliard Navier-Stokes equations: Second-order, energy-stable numerical methods on adaptive octree based meshes

Makrand A Khanwale, Kumar Saurabh, Milinda Fernando +4

We present a fully-coupled, implicit-in-time framework for solving a thermodynamically-consistent Cahn-Hilliard Navier-Stokes system that models two-phase flows. In this work, we e…

A nonlinear weak constraint enforcement method for advection-dominated diffusion problems

Roberto J. Cier, Sergio Rojas, Victor M. Calo

We devise a stabilized method to weakly enforce bound constraints in the discrete solution of advection-dominated diffusion problems. This method combines a nonlinear penalty formu…
