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.
Fix tool enables you to check and fix intersections, crossings and penetrations between components and intersect components
that are classified as Faults.
The Perforation tool allows the user to automatically build a complete hexa-mesh perforation model by setting the
desired parameters in just a few clicks, to evaluate the impact of perforations on well productivity.
Auto contact generation works independently of whether the model is FE (element) or geometric (CAD) based. When you
choose to generate contacts automatically, contact bodies are identified, respective contact pairs and contact sets
are created.
Use the Voxel: Create tool to create voxel meshes.
From the Define group, select Tetra > Voxel > Create.
A guide bar will appear.
Define voxel options.
On the guide bar, click .
The Options dialog opens.
In the Voxel size field, enter a value.
In the Create voxels at: field, select one of the following:
Intersections and Voids (default)
Voids only
Intersections only
Select include volume entities.
Include volume entities define the outer bound of the package space. All
space within the include selection will have voxels created unless otherwise
specified.
Important: You must select at least one
include.
Components, elements, lines, surfaces, and solids are supported. Change the
entity type from the guide bar selector.
Optional: Select exclude volume entities.
Exclude volume entities define the non-design parts and/or subsystems. All
space within the exclude will be exempt from having voxels created within
it.
Components, elements, lines, surfaces and solids are supported. Change the
entity type from the guide bar selector.
Optional: Select or create a symmetry.
Symmetry allows the voxel design space to be generated using one or more
symmetry planes. Once the voxels are created and edited as necessary, the
voxels can then be reflected to generate the full model.
Select an existing symmetry.
Create new symmetry by clicking Create New and
using the Vector tool.
Click Create.
Voxels are generated at both the intersection of the part(s) and fills the voids of
the appropriate package space.
When the voxels are generated two new entities are created and append to the Model
Browser, Design Spaces and Symmetry Planes. Symmetry Planes will only appear if the
Symmetry option is used during voxel generation. Both of these entities store and
persist the necessary information for further downstream use, and are saved in
the.hm binary file. For example; if the non-design package
space changes, you can simply select and update the exclude entities and re-generate
the voxels.
Modify the Design Space entity by selecting it in the browser and then invoking the
Voxel: Create tool. Changing the voxel size, the include/exclude content, and
symmetry usage is all possible. The Output Components can only be modified in the in
the Model Browser, Entity Editor. Voxels can be organized into one or many
components to group the regions into representative manufacturable parts, such as
castings or machined parts for example. Typically, these sort of design variables
(or regions) have specific topology optimization options applied such as draw
direction for improved manufacturability.
The most efficient way to handle load case setup is to have the boundary conditions
organized in a separate Include file. If the boundary conditions are applied via
RBE’s, then the RBE’s should be included in the Include as well. Upon voxel creation
or update, the Include can be imported and the RBE’s can be equivalenced to the new
or updated voxels. This process allows for design changes to occur and facilitates
quick boundary condition reapplication.
