A Combined Finite Element and Finite Volume Method for Liquid Simulation

CoRR, 2023
We introduce a new Eulerian simulation framework for liquid animation that leverages both finite element and finite volume methods. In contrast to previous methods where the whole simulation domain is discretized either using the finite volume method or finite element method, our method spatially merges them together using two types of discretization ...

Unified Framework for Finite Element Assembly

, 2009
At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs.

Three-Dimensional Explicit Finite Element Simulation of Piled-Raft Foundation

Journal of Engineering, 2020
This paper aims to validate a proposed finite element model to be adopted in predicting displacement and soil stresses of a piled-raft foundation. The proposed model adopts the solid element to simulate the raft, piles, and soil mass.

Construction and finite element simulation of a square laser loading model that can replace circular spot superposition in laser peening forming

Journal of Advanced Mechanical Design, Systems, and Manufacturing
In order to explore an efficient, accurate, and convenient finite element simulation method for laser peening forming, a square laser loading model was constructed by studying the loading feature unit of the circular spot superposition model, which can ...
