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…
Boundary treatment algorithms for meshfree RANS turbulence modeling
Mohan Padmanabha, Jörg Kuhnert, Nicolas R. Gauger +1
In this paper, we propose improved wall-treatment strategies for meshfree methods applied to turbulent flows. The goal is to enhance wall-function handling in simulations of high-R…
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…
Volume and Mass Conservation in Lagrangian Meshfree Methods
Pratik Suchde, Christian Leithäuser, Jörg Kuhnert +1
Meshfree Lagrangian frameworks for free surface flow simulations do not conserve fluid volume. Meshfree particle methods like SPH are not mimetic, in the sense that discrete mass c…
