Additional Meshing Tools
Meshing Tools
Besides the automated meshing tools, there are several semi-automated meshing
tools to generate hex and wedge elements using,
Extrude
Revolve
Sweep
2.5D Meshing
Profile
This section covers details on how to use these tools.

Extrude
Application | Geometry | Body | Create | Extrude
Extrude option is used to create geometry in the specified direction.
Solid body will be created when we select faces.
Sheet body will be created when we select edges.
Wire body will be created when we select vertices
Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.
Faces / Edges / Vertices will be extruded in the specified direction, distance and
with respect to the number of layers are specified.
Inflate – It will extrude the given face in both direction (+ve and –ve) with respect
to the given magnitude.
Direction can be
Normal to Elem
Radial

Extrude - Plane
Faces / Edges / Vertices will be extruded up to the plane in the specified direction
and the layers.

Revolve
Application | Geometry | Body | Create | Revolve
Revolve option is used to create axi-symmetric geometry.
Solid body will be created when we select faces.
Sheet body will be created when we select edges.
Wire body will be created when we select vertices

Revolve - Basic
• Faces / Edges / Vertices will be revolved with respect to an axis for the specified angle
and thickness will vary depending on the number of layers specified.

Profile
The profile is defined by a set of nodes selected by the user.
The shape of the face is defined by a polygon using the selected nodes in a sequence.
This feature allows the sweeping of the profile.
Once a profile is created, it can be saved and imported for latter use.
Bolts, liners, valve seats can be defined using a profile and stored.

Profile
Using the Start / End / Restart buttons, select a set of nodes.
Specify the angle of revolution and the axis about which the profile is to revolve.
Enter the number of elements and the mesh size.
