The primary objective of this work is to develop and test a new convergence acceleration technique we call multicloud. Multicloud is well-founded in the mathematical basis of multigrid, but relies on a meshless operator on coarse levels. The meshless operator enables extremely simple and automatic coarsening procedures for arbitrary meshes using arbitrary fine level discretization schemes. The ...

A meshless method for parameterizing point clouds using convex combination mapping and mean value coordinates has been introduced by Floater et al. The advantage of the method is that only a sparse linear system has to be solved and the resulting parameterization is usually injective. However, in the presence of concave boundaries the convex combination mapping is not always well defined and of...

In this paper, a method based on a combination of an optimization of directions of orthotropy, along with topology optimization, is applied to continuum orthotropic solids with the objective of minimizing their compliance. The spatial discretization algorithm is the so called Meshless Local Petrov-Galerkin (MLPG) “mixed collocation” method for the design domain, and the material-orthotropy orie...

This paper proposes a novel meshless boundary method called the singular boundary method (SBM). This method is mathematically simple, easy-to-program, and truly meshless. Like the method of fundamental solutions (MFS), the SBM employs the singular fundamental solution of the governing equation of interest as the interpolation basis function. However, unlike the MFS, the source and collocation p...

A Meshless Radial Basis Function Method for Fluid Flow with Heat Transfer K Nagamani Devi1, D.W. Pepper2 Summary Over the past few years, efforts have been made to solve fluid flow and heat transfer problems using radial basis functions. This approach is meshless, easy to understand, and simple to implement. Preliminary results indicate accuracies on the order of finely meshed conventional tech...

This paper presents a fast approach for computing tight surface bounds in meshless animation, and its application to collision detection. Given a high-resolution surface animated by a comparatively small number of simulation nodes, we are able to compute tight bounding volumes with a cost linear in the number of simulation nodes. Our approach extends concepts about bounds of convex sets to the ...

In this work we review the opportunities given by the use of local maximumentropy approximants (LME) for the simulation of forming processes. This approximation can be considered as a meshless approximation scheme, and thus presents some appealing features for the numerical simulation of forming processes in a Galerkin framework. Especially the behavior of these shape functions at the boundary ...

A new numerical method for the full-wave physical modelling of semiconductor devices using a combination of the meshless and finite-difference time-domain (FDTD) approaches is described. The model consists of the electron equations for the active part and Maxwell’s equations for the electromagnetic effects, which describe the complete behaviour of a high-frequency active device. The uncondition...
