چکیده
We apply the recently developed least squares stabilized symmetric Nitsche method for enforcement of Dirichlet boundary conditions to finite cell method. The in combination with stabilization leads a positive definite stiffness matrix and relies only on elementwise stabilization, which does not lead additional fill in. prove priori error estimates bounds condition numbers.

First Order System Least Squares with inhomogeneous boundary conditions
Thanks to (1.1), the bilinear form on X×X at the left hand side is bounded, symmetric, and elliptic, and the right-hand side defines a bounded functional on X . From the Lax-Milgram lemma, we conclude that (1.2), and so the least-squares problem, has a unique solution u∈X that depends continuously on f ∈Y ′. Whenever the equation Gu= f has a solution, i.e., f ∈IG (consistency), it is the unique...
متن کاملThe complex polynomial method with a least-squares fit to boundary conditions
We present a new application of the complex polynomial method variant of the complex variable boundary element method. Instead of fitting the boundary conditions using collocation points, we minimize the error of fit in the l2 norm to minimize the least-squares error. This approach greatly enhances the utility and efficiency of the method, allowing us to apply the method to a variety of enginee...
متن کاملRecursive least squares with stabilized inverse factorization
Recently developed recursive least squares schemes, where the square root of both the covariance and the information matrix are stored and updated, are known to be particularly suited for parallel implementation. However, when finite precision arithmetic is used, round-off errors apparently accumulate unboundedly, so that after a number of updates the computed least squares solutions turn out t...
متن کاملLeast-squares finite-element lattice Boltzmann method.
A new numerical model of the lattice Boltzmann method utilizing least-squares finite element in space and Crank-Nicolson method in time is presented. The new method is able to solve problem domains that contain complex or irregular geometric boundaries by using finite-element method's geometric flexibility and numerical stability, while employing efficient and accurate least-squares optimizatio...
متن کاملA Least-Squares/Fictitious Domain Method for Linear Elliptic Problems with Robin Boundary Conditions
In this article, we discuss a least-squares/fictitious domain method for the solution of linear elliptic boundary value problems with Robin boundary conditions. Let Ω and ω be two bounded domains of Rd such that ω⊂Ω. For a linear elliptic problem in Ω\ω with Robin boundary condition on the boundary γ of ω, our goal here is to develop a fictitious domain method where one solves a variant of the ...
