Point Cloud Quality for Meshfree Methods
Mohsen Abdolahzadeh, Oleg Davydov, Isabel Michel +1
Mesh quality is very well studied and widely used to quantify a good mesh. In contrast, a systematic study of quality of meshfree point clouds is lacking. This gap makes it difficu…
Meshfree Snow Modelling using a Modified Cam-Clay Approach
Erik Schlesinger, Chaitanya Sanghavi, Jörg Kuhnert +2
Snow is a complex geomaterial whose macroscopic response is governed by density, temperature, and the topology of its evolving microstructure. Its mechanical behavior spans elastic…
An Overview of Meshfree Collocation Methods
Tomas Halada, Serhii Yaskovets, Abhinav Singh +3
We provide a comprehensive overview of meshfree collocation methods for numerically approximating differential operators on continuously labeled unstructured point clouds. Meshfree…
Higher-Order Generalized Finite Differences for Variable Coefficient Diffusion Operators
Heinrich Kraus, Jörg Kuhnert, Pratik Suchde
We present a novel approach of discretizing variable coefficient diffusion operators in the context of meshfree generalized finite difference methods. Our ansatz uses properties of…
