A Mixed Hybrid Finite Volume Scheme For Incompressible Navier-Stokes

Mixed Virtual Elements (MVE) is an innovative class of discretization schemes allowing solution of PDEs on virtually any mesh; such schemes stem from the idea of building discrete operators mimicking certain key…

Numerical simulation and experimental validation of guided ditching tests

The oblique water entry of structures with high horizontal speed is investigated in this work. First, the necessity of aircraft ditching analysis as well as the requirements for numerical tools to simulate aircraft…

Advancements of Virtual Prototyping in the World of Demanding Regulations

Regulations in safety and fuel efficiency are putting more and more pressure on the Automotive Industry to move towards lightweight solutions. Consequently, innovative research and a 3G engineering approach (gage, grade…

Effects of Manufacturing Process in Crash Simulations

This article describes an impact of a manufacturing, which can significantly change real parts behavior. The influence of technology process is neglected in regular simulations. However, advanced finite elements solvers…

Enhancements and validation of FPM fluid structure interaction module applied to curtain airbag deployment

Models to represent in position situations based upon uniform pressure assumptions are well established and have been used extensively in the automotive industry for more than 15 years. More recently, in the beginning…

Aero Forming - An Introduction of Collaborative Engineering

The decrease of physical prototypes and the growing power of simulation in the design process require greater control in the design chain calculation. This is the main reason for the arrival of SDM in the perimeter of…

Collaborative development of finite element models for Honeycomb crash test barriers: Crash / Volkswagen

Deformable barriers used in car crash testing are based on aluminium honeycomb blocks covered by aluminium plates. These structures, that largely deform and tear during crash tests, represent a challenge for the…

Conjugate heat transfer in hypersonic flows

In certain applications, different regions of the computational domain experience flow conditions/physics that are so different that it is very difficult for a single solver to produce sufficiently accurate results…

Methodology to predict transient engine compartment air temperature following engine shut down

Cooling and heat protection of the engine compartment significantly impact the performance of combat vehicles. An increased heat load occurs during soak-back after engine shut down, where the fans are shut down. Heat is…

Multiphysics modeling of high density IC encapsulation

A multi-physics modelling approach for simulating the plastic encapsulation of high density IC packages is presented. This modelling approach is used to predict the two-phase flow of a curing resin, the heat transfer in…
