Collectors are named organizational containers for collected entities. Collected entities are nameless entities which must
reside within one, and only one, collector. Collected entities are mutually exclusive to a collector.
Morph constraint entities restrict or prescribe the movement of nodes during morphing, with a variety of available
methods and dimensional values. These constraints are valid across all available morphing approaches and can be individually
activated or deactivated at any time, even in between morphs or applying shapes.
Morph volume entities are highly deformable six-sided prisms which surround a portion of the FE mesh, and can be used
to manipulate a mesh by manipulating the shape of the morph volume.
Browsers provide a structured view of model data, which you can use to review, modify, create, and manage
the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting,
which enhance your ability to navigate and interact with the model data.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing
parts. The current capabilities are focused on stiffening parts.
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or
remeshing and without design variables.
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as
corporate PLM systems to access CAD data or publish simulation data.
Domain entities divide the model into different domains during morphing.
Each domain contains either elements (for 1D, 2D, 3D, or general domains), a series of
nodes (for edge domains), or a group of nodes (for global domains).
The shape of a domain changes when the handles associated with a domain move, which in turn
changes the position of the nodes inside those domains.
Domains do not have an active or export state.
Domain Types
For 1D, 2D, and 3D domains, only elements of the appropriate type will be assigned to the
domain. If selected elements of the correct type are already assigned to another domain,
then they will be reassigned to the new domain.
Handles will automatically be created at the ends of the edge domains.
1D Domain
Group of 1D elements, such as bars and rigid elements.
2D Domain
Group of shell elements. When 2D domains are created, edge domains will also be
created around the edges of the elements for the domains.
Figure 1 shows a 2D domain
that has been created from the selected elements. You only need to select the elements
that you want to be in the new domain. The elements are automatically assigned to the
new domain, edge domains are created around it, and handles are added at appropriate
positions on the edge domains. The 2D domain created allows for the creation of a bead
by moving the two handles at the ends of the edge normal to the plane of the
elements.
3D Domain
Group of solid elements. When 3D domains are created, 2D domains will be created on
their faces and edge domains will be created around the edges of the 2D domains.
General Domain
General domains can contain any type of element (1D, 2D, or 3D), but edges or faces
are not created along with the general domain. General domains will respect 2D and
edge domains and you may create edge domains inside general domains if you desire.
Handles will be created for general domains where the domains contact other elements
whether those elements are in domains or not. Where the general domain contacts
elements outside of domains, a handle is created at every node on the interface. Where
general domains contact elements in other domains, handles will be created at logical
locations to ensure control of the general domain. Once created, general domains can
be morphed just like any other domain, even though they may contain different element
types.
Figure 2 shows a general
domain that has been created for a connector consisting of two rigid spiders and a
hexa element. Note the four-rectangle shaped icon (in the center) for the general
domain. Two handles have been manually added at either end of the domain so that the
domain can be morphed as needed. Moving either handle will cause the entire domain to
stretch evenly across its length.
Note: It is possible to include the shell elements as part of the general domain
in addition to the hexa and rigid elements.
Edge Domain
Series of nodes that are commonly found along the edges of 2D and 3D domains. You
are not able to create edge domains that are not attached to any 2D, 3D, or general
domains.
Figure 3 shows an edge domain
that has been created for the selected nodes. The nodes should be selected in order
following the path of the edge domain without skipping over any nodes. HyperMesh automatically adds handles at the ends of the edge
domain at points along the length where the angle and curvature direction change above
the set threshold. The edge domain created allows for the creation of a bead by moving
the two handles at the ends of the edge normal to the plane of the elements.
Global Domain
Group of nodes.
You may create more than one global domain in a model, but no node may belong to
more than one global domain. Global handles only affect the nodes assigned to their
global domain.
If you only need to change the shape of your model in a general way, then you only
need to create a global domain. For large models, automatically generating local
domains for the full model, such as using the generate auto function, is time
consuming and possibly unnecessary. If you only need to change a part of the model,
then you only need to create domains for that part.
When creating a global domain, you have the option of having global handles
automatically generated for you. HyperMesh will place
these handles at the eight corners of a box surrounding the model and at areas of peak
nodal density within the model.
