| Enabled for Volume Mesh / Surface Mesh / Wrapping
Mesh |
Enable refinement zones for volume meshing, surface meshing,
and/or adaptive wrap meshing. |
| Element Size |
Define the target element size for mesh inside of the
refinement box. Note: The actual mesh size will vary in order to
maintain mesh connectivity at the edges of the box. In
the example below, the boundary region has been selected as With
BL (float) and remesh, therefore the region included in the
refinement box has been remeshed with the elements size assigned
to the refinement box. |
| Shape |
Define the refinement zone shape.
- Box
- Is defined by:
- By Center and Size
- Use the selector to select a center node and
specify the x, y, and z dimensions of each side of
the box.
- Example: A size of 5 creates a 5 x 5 x 5 box
centered around the center node.
- By Two Nodes
- Use the selector to select two nodes which
represent opposite corners of a cubic volume.
- By Four Nodes
- Use the selector to select a base node and
three additional nodes. The four selected nodes
cannot be coplanar. The base node, N1, and N2 form
a triangle, which is then flipped 180 degrees to
form a rectangular base for the refinement box.
The vector from base node to N3 defines the
refinement box's height and direction from the
base.
- By Eight Nodes
- Use the selector to select all eight nodes of
the refinement box. The order of the box will be
corrected internally if defined incorrectly.
- By Element Volume
- Use the elems selector to select the elements
that define the volume. Define a scaling factor to
scale the elements enclosed in the box. A scale
factor of 1 creates the smallest possible box that
can still enclose the selected elements, whereas a
factor of 2 creates a box twice as large in every
dimension.
- Cone
- Defined by the lower circular face center (as a node
or coordinates), lower circular face radius,
cylinder height, and normal axis of the
cylinder.
- Cylinder
- Defined by the lower circular face center (as a node
or coordinates), lower circular face radius,
cylinder height, and normal axis of the
cylinder.
- Ellipsoid
- Defined by four nodes: the center node and three
other nodes which define the radius in each
direction and also the orientation.
- Frustum
- Defined by the lower circular face center (as a node
or coordinates), lower circular face radius, top
circular face radius, cylinder height, and normal
axis of the cylinder.
- Sphere
- Defined by the center (as a node or coordinates) and
radius.
- Wake
- Is defined by:
- Element size
- Size for refinement. This is ignored if the
refinement size method is “Table”.
- Refinement method
- Constant: Constant refinement size (“Element
size”) is applied.
- Table: Define refinement size as a function of
distance from selected geometry. Enter the number
of table rows then enter distance vs refinement
size.
- Selection
- Select surfaces, lines, points, or nodes.
- Direction
- Refinement happens along defined vector.
- Limiting distance
- Refinement happens from selected geometry to
distance defined here.
- Draft angle
- Add angle to wake refinement.
- Part
- Defined by an element size, selected geometry, and a
specified limiting distance.
