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


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

Direction

Spherical

Extrude - Distance


Before Extrude

After Extrude

Extrude - Distance


Extrude - Plane

Faces / Edges / Vertices will be extruded up to the plane in the specified direction

and the layers.

Direction can be

Normal to plane

Direction


Extrude - Plane


• Extrude will be done between the two set of faces / edges / vertices having identical

mesh pattern.

Extrude - Between


Extrude – upto surface

Faces / Edges / Vertices will be extruded up to the surface in the specified

direction and the layers.

Direction can be

Normal to Elem

Direction


Extrude – upto surface


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.


Revolve - Between

• Revolve will be done between the two set of faces / edges / vertices having identical

mesh pattern.


Revolve - Between


Revolve – upto surface

Faces / Edges / Vertices will be revolved up to the surface.

We can specify any number of limit faces.


Revolve – upto surface


Application | Geometry | Body | Create | Sweep Sweep option is used to create geometry with respect to the guide edge.

Sweep


Sweep - Basic

Faces will be swept with respect to the guide edge.

Supported only for four and three edged faces.


Sweep - Basic


Sweep - Between

• Sweep will be done between the two set of faces having identical mesh with respect to

the guide faces / edges.


Sweep - Between


Sweep – Helix

• Helix option is used to create geometry like drill, spring etc


Sweep – Helix


Application | Geometry | Body | Create | 2.5DMeshing

2.5D Meshing option is used to create hex / wedge / tet elements with respect to

the side faces.

2.5D Meshing


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.
