Function

Offset Mesh creates elements by offsetting a 1D element to a 2D element, a Edge to a 2D element, and a 2D element to a 3D element

Select the 1D elements (Mesh, Element) that will be offset

 

Offset Direction

Positive Normal

Define the offset direction by the positive normal direction of selected objects.

Negative Normal

Define the offset direction by the negative normal direction of the selected objects.

Both Direction

The selected objects will be offset by both the  positive and negative directions.

 

Uniform

Offset the selected object at a uniform distance by the number of times specified.

Offset

Enter an offset distance.

Number of Times

Enter the number of offsets.
 

Non-uniform Offset

Extrude the selected nodes by specifying non-uniform distances entered as a function.  Enter multiple distances separated by commas (,).  For repetition, use the input format as “the number of times @ distance”.  Example) 30,20,2@15,20

 

Source Mesh

Specify what will be conducted to Source Meshes after it has been extruded.

None

Leave the Source Meshes as it is.

Delete

Delete the Source Meshes.

Move

Move the Source Mesh to the end of extrusion.

Copy

Attribute

 

Mesh Set

User Defined Mesh Set

User can specify the number of offsets per set. If one number has been entered, it will uniformly register generated mesh by the number of offsets. If more than one number has been entered, it will non-uniformly divide the Mesh Set by the given numbers. The sum of the numbers should not be greater than the total number of offsets.

Generate 1D Elements from Nodes  by Extruding to a Given Direction

 

 

 

 

<Instruction>

 

1. Select 9 edges which are used to generate 2D quadrilateral elements. All edges must be seeded before.

2. Make sure Offset Direction is set to Positive Normal.

3. Make sure offset method is set to Uniform.

4. Enter 10 in Offset.

5. Enter 2 to Number of Times.

6. Click button to assign Attribute to 2D elements.

7. Click [OK] button.

 

Note

1. Offset direction is determined automatically by edges normal direction.

2. By using Preview function, check whether offset direction is properly selected. If not, reverse its normal direction.

3. A single straight edge would fail to offset. The normal direction of a straight edge can not be determined properly.

<Instruction>

 

1. Select 6 element(s) which are used to generate 2D elements.

2. Select Extrusion Direction (Refer to Advanced Selection for Direction Definition).

3. Check on Non-uniform in Offset method.

4. Enter 2@25, 30, 40  in Offset.

5. Check on Two Way Extrusion.

6. Click button to assign Attribute to 2D elements.

7. Click [OK] button.

 

1. Select 205 element(s) which are used to generate 3D Element.

2. Set Offset Direction to Negative-Normal.

3. Set offset method to Non-Uniform.

4. Enter 7, 13  to Offset

5. Enter 2 to Number of Times

Note

1. Offset direction is not allowed to choose freely. Offset direction is set automatically by normal direction of element.
