Fluid-Solid Coupling

posted in: | 0

The immersed body method is employed which solves two separate sets of governing equations for the solid and the fluid, and the iterative coupling is achieved through conservative mesh interpolation using the “supermesh” method O’Farrell et al (2013). The schematic … Continued

Particle Shape Library

The majority of the research required to create an effectively functioning shape library software package, hosted by Sourceforge within the VGW package was created by Dr Xavier Garcia as a by-product of his PhD research at Imperial College. Numerical simulation that will … Continued

Plasticity Model

posted in: | 0

Plasticity models have been developed for implementation in FEMDEM by Nikos Karantzoulis. Supervisors were John-Paul Latham, Jiansheng Xiang and Bassam Izzuddin.   Numerical solution of Governing Equations The general continuous equations of elasto-plasticity are discretised by applying a fully implicit (backward) Euler scheme, … Continued

3D FEMDEM

posted in: | 0

Prior to 2005, the combined finite-discrete element method was mostly based on linear tetrahedral finite elements and triangular elements in 2D problems. Locking problems associated with these linear elements can seriously degrade the accuracy of their simulations. Many complex shaped … Continued
