HFSS15: Assigning Length-Based Mesh Refinement Inside Objects

To instruct HFSS to refine every face of an object and its interior:

1. Select the object you want HFSS to refine.

2. Click HFSS>Mesh Operations>Assign>Inside Selection>Length-Based.

The Element Length-Based Refinement dialog box appears.

3. Type a name for the mesh operation in the Name text box or accept the default name.

4. To restrict the length of the tetrahedral element edges inside the object:

a. Select Restrict Length of Elements.

b. Type the maximum length of the edges inside the object in the Maximum Length of Elements text box.

The default value is set to 20% of the maximum edge lengths of the bounding boxes of each selected object’s faces.

HFSS will refine the element edges inside the object until they are equal to or less than this value.

5. To restrict the number of elements added during the refinement inside the object:

a. Select Restrict the Number of Elements.

b. Enter the Maximum Number of Elements to be added.

c. Click OK.

When the mesh is generated, the refinement criterion you specified will be used. If the maximum number of elements are reached, it may result in some elements exceeding the requested maximum element length.

You can also specify Initial Mesh Settings to apply to all objects; however, if you apply separate surface approximation mesh operations to specific objects, the object settings take precedence over the general setting.
