creating extremely large, detailed
models easily


Tutorial & Examples available

FSI Overview

+

Structure Model

Fluid/ Explosive

Post Processing

Shock 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”


When saved, the defined list is shown
as defined in the Card list
