specific applications– Provide a streamlined process in a consolidated

menu group– Application focused modeling modules

• PreSys + VPG Modules are implemented as ‘plug-ins’– FSI (Fluid Structure Interaction) Module– Drop Test Module – Safety Module– Structure Module

FSI Module

• Allows users to more easily build LS-DYNA fluid-structure interaction models using the ALE method

• Used for blast models, airbags, fuel sloshing, alternative energy, medical

• Easy coupling of Fluid & Structure Models

• 64-Bit implementation to make creating extremely large, detailed models easily

• Tutorial & Examples available

FSI Overview

+

Structure ModelFluid/ Explosive

Post ProcessingShock Tube Model

• The proportion of model: 1, 1/2,1/4

• The shape and relative position of explosive and zones

• The dimension of explosive

• The dimension and material of Zone 1

FSI Setting - Mesh Generation

• The dimension and material of Zone 2

• The user can define multiple transition regions to ensure the mesh size compatibility between explosive source and medium.

•A preview mode is available to display the transition regions before generating the mesh.

FSI Setting - Define Multiple Transition Regions

• In this transitional region, the element size is gradually transitional

• The ratio value is the theoretical ratio value between the first element size and the last element size in the region.

FSI Setting -Ratio Between Transition Regions

FSI Setting - Define the Material and the Property

• The explosive and the zones have been assigned the common material and property.

• The user can change the material or property by clicking the corresponding button.

FSI Setting - Define the Keyword for Simulation

• All the keywords related to FSI are listed in this tab

• A keyword editor is displayed when the user double clicks on “keyword”
