Introduction to ANSYS DesignModeler

Customer Training MaterialGoals

Demonstrate the process of

creating geometry of a Radiator

(Heat Exchanger) using pattern &

thin/surface tools.

The basic steps involved in creationof this geometry are:

1. Creation of base geometry by

sketching and extrusion

2. Modifying the base geometry

using chamfer

3. Creating multiple copies of body

using pattern

4. Converting solid body into hollow

body by using thin/surface

[Modeling] > Extrude

Toolbar: Extrude

Extrude the BaseSketchwith a

distance of 700 mm

Click on Generate tab to complete

the process

[Modeling] >Create>Chamfer

Chamfer-1: Select the edges

as shown and Left-rightdistance

of 28 & 8 mm respectively.

Customer Training MaterialUsing Pattern for Creating Multiple Bodies

[Modeling] >Create>Pattern

Pattern: Create a linear pattern of the

existing body by using an Offset

distance of 80 mm and number of

Copiesas 5.

Finally click on generate tab to

complete the process.

Customer Training MaterialPlane Creation and Sketching

[Modeling] >Create>New Plane

Plane: Create a plane by transforming YZ plane by 30

mm in Z-direction and 38 mm in Y-direction. Finally

click on generate tab to complete the process

Insert a sketch on this plane by using

[Sketching] > Sketch2

Circle1: Draw a circle of 60 mm diameter with thecenter at plane origin.

Circle2: Draw another circle of 60 mm diameter on the

plane as shown.

Dimension the distance between the circle as 624

mm. Click on generate to complete the process.

Customer Training MaterialSketching

[Modeling]

Insert one more sketch in Plane4

by using icon

[Sketching] > Sketch4

Circle3: Draw a circle of 36 mm

diameter at the center at plane

origin. Circle4: Draw another circle of 23

mm diameter at the center of Circle 2

of previous drawn sketch
