This paper describes the numerical analysis of unsteady aerodynamics of a radiator mounted car model in dynamic pitching motion using LS-DYNA ICFD solver. Large-Eddy simulations with ALE method and porous media modeling were performed ...

There are many different contact algorithms currently implemented in LS-DYNA, each having various options and parameters. I will discuss only a few of them. Much of what is covered will only apply to the MPP version of LS-DYNA. I will ...

With increased mechanical and functional requirements put on many parts produced by the manufacturing industry, the numerical simulation of the process has gained importance within the last years. The main objective when applying ...

Accurate modeling of a truck tire for predicting dynamic characteristics requires an adequate representa- tion of its composite plies. This study compares two approaches in modeling the multi-layered structure of a rolling radial-ply ...

Porous metals have been increasingly used in modern engineering applications over the past decades due to their multi-functionality and attractive combination of mechanical and thermal properties [1]. The understanding of their ...

The LS-TaSC Version 3.1 topology and shape design tool is presented. The presentation introduces the multi-point numerical derivatives scheme that allows constrained optimization using the mass fractions and load case weights as ...

Accurate modeling of a truck tire for predicting its dynamic characteristics requires an adequate representation of its composite plies. This study compares two approaches in modeling the multi-layered structure of a rolling ...

Simulating the masticatory system during chewing, clenching and bruxism, requires a model that captures the dynamical behavior of its different components: the mandibula and maxilla, the temporomandibular joint (TMJ), the teeth, the ...

LS-DYNA offers a wide variation of material cards to cover different needs in diverse applications. However, choosing the most proper material model among 250 keywords can be quite deceptive. Therefore, an algorithm has been developed ...

LSTC is continually improving the capabilities and performance of Implicit especially in the distributed memory computing environment. This talk will review recent improvements such as (a) removing serial memory restrictions with a ...
