NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020!

CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore future issues, including:
-What is the future for engineering analysis and simulation?
-Where will it lead us in the next decade?
-How can designers and engineers realize its full potential?
What are the business, technological, and human enablers that will take past successful developments to new levels in the next ten years?

Resource Abstract

Each method comes with its own strengths and its own limitations, which may be explained by the underlying physical assumptions, the discretization approaches and the numerical techniques…

Depending on the problem to solve, the “ideal” solver may not be the same.

This presentation intends to provide some background information and ease which solver to choose.



Instead of tackling one-by-one the wide diversity of CFD solvers, the main differentiating approaches and techniques will be explained, and their strengths and weaknesses underlined.

From technical characteristics to physical capabilities, from numerical aspects to meshing user experience, the suitability of each methods in addressing specific application fields will be explained.

A special focus will be placed upon the "conventional" FVM (Unstructured body-fitted Finite Volume Methods), the octree-based immersed-boundary FVM, the LBM (Lattice-Boltzmann Methods) and the SPH (Smoothed Particle Hydrodynamics) method.



With all these strengths and limitations in mind, the applicative capabilities of the SPH methods will be illustrated with several representative cases from the automotive and aerospace industries.

Note that multi-fluid flows, thermal analysis, surface tension, cavitation, Fluid-Structure Interaction (FSI), CFD-method coupling... may all be involved!
