Use the Create Points/Nodes tool to create and edit points/free nodes on geometry surfaces and lines or in space. Points and nodes can be used
to establish reference locations for geometry construction and meaningful snap locations for use with other tools.
A surface represents the geometry associated with a physical part. A surface is a two-dimensional geometric entity that
may be used in automatic mesh generation.
Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in
automatic tetra and solid meshing.
Use the Revolve tool to create axisymmetric revolved regions around select solid bodies. This is useful for creating
regions around rotating bodies like fans, impellers, wheels, and so on.
Use the Midsurfaces tool to extract the midsurface of sheet metal stampings, molded plastic parts with ribs, and other parts that have
thickness clearly smaller than width and length.
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE
studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Create evenly spaced or biased nodes by interpolating between existing nodes in
space, on a surface, or on a curved or straight line.
From the Topology ribbon, click the Create Points/Nodes tool.
From the Geometry ribbon, click the arrow next to the
Create tool set, then select
Create Points.
From the drop-down menu on the guide bar, select
Interpolate Nodes.
From the second drop-down menu on the guide bar, select
from the following:
Option
Description
Nodes
Select at least two nodes to interpolate nodes between.
Note: Input nodes are specified as a node
list, with each node considered as a pair with the next node
in the list.
In the Number of nodes field, enter the number of nodes to
create on a straight line between each selected node pair.
Select a bias style: linear,
exponential, or bell
curve.
In the Bias intensity field, enter a value.
Note: Nodes are created in 3D space, and not
merely on geometry.
Lines
Select lines and at least two nodes to interpolate nodes
between.
Use the Node List selector to select existing nodes.
Input
nodes are specified as a node list, with each node
considered as a pair with the next node in the list.
Note: Input nodes are not required to
lie on the selected line, as all input nodes are first
projected onto the line.
In the Number of nodes field, enter the number of nodes to
create between each selected node pair.
Select a Bias style: linear,
exponential, or bell
curve.
In the Bias intensity field, enter a value.
Locations
Select at least two locations to interpolate nodes between.
In the Number of nodes field, enter the number of nodes to
create between each selected node pair.
Select a Bias style: linear,
exponential, or bell
curve.
In the Bias intensity field, enter a value.
Surfaces
Select surfaces and at least two nodes to interpolate nodes
between.
Use the Node List selector to select existing nodes.
Input
nodes are specified as a node list, with each node
considered as a pair with the next node in the list.
Note: The nodes are not required to lie
on the selected surface, as all input nodes are first
projected onto the surface.
In the Number of nodes field, enter the number of nodes to
create between each selected node pair.
Select a Bias style: linear,
exponential, or bell
curve.
In the Bias intensity field, enter a value.
When complete, from the guide bar, click one of the
following:
- Apply and stay in the tool.
- Apply and close the tool.
- Exit the tool without applying.
The following figures illustrate the effect of adding five nodes between the end
nodes of a line using the different bias styles with a bias intensity of 5.0.
Nodes are created in 3D space, and not merely on geometry as shown in the previous
images.
The following figure illustrates nodes interpolated along a curved line. Five nodes
created between two input nodes along a curved line, using linear biasing.
The following figure illustrates nodes interpolated on a surface. The highlighted
opposing corner nodes have seven interpolated nodes created between them, using
Bellcurve biasing.
