Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing
process using the Verification and Comparison tools.
1D mesh that allows accurate testing of connectors, such as bolts, and similar rod-like or bar-like objects that can
be modeled as a simple line for FEA purposes.
Volume mesh or "solid meshing" uses three-dimensional elements to represent fully 3D objects, such as solid parts
or sheets of material that have enough thickness and surface variety that solid meshing makes more sense than 2D shell
meshing.
You can select multiple solids for solid map meshing provided that each individual solid is in fact mappable. However,
the meshing engine cannot always mesh every selected solid in a single operation, even when all the selected solids
display as mappable.
Before you can successfully solid mesh a model, ensure that the solids have been partitioned so that they are either
one directional or three directional mappable.
Acoustic Cavity meshing generates a fluid volume mesh used to calculate the acoustic modes (or standing waves) inside
the air spaces of a vehicle or similarly enclosed structural model.
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality and create, edit, and apply
shapes for subsequent design optimization studies.
Volume mesh or "solid meshing" uses three-dimensional elements to represent fully 3D objects, such as solid parts
or sheets of material that have enough thickness and surface variety that solid meshing makes more sense than 2D shell
meshing.
Create a new 3D mesh from a single, mappable solid volume.
Before you being, ensure that the solids have been partitioned so that they are
either one directional or three directional mappable. Refer to, Partition Solids for Mappability.
Also make sure you have an existing 2D mesh, which will be used to extrapolate the 3D
solid map mesh. When creating mesh from the One Volume subpanel, a 3D mesh can be
automatically created directly on solids as long as the solids you select are
already mappable.
From the Mesh ribbon, 3D Mesh tools, click the Hex tool.
Select the One Volume subpanel.
For volume to mesh, select the solid/surface to mesh.
Define the direction of mesh mapping.
For source hint, select the “beginning” surface.
For dest hint, select the “ending” surface.
For source shells, select the type of elements to use when creating the
resulting output solid mesh.
This defines the 2D mesh on the initial surface of the solid, and will
dictate the output element type when meshing the solids.
Choose mixed to use hexa and penta
elements.
Choose quad to create hexa elements.
Choose trias or R-trias to
create only penta elements (right-angle pentas in the case of
R-trias).
Select which component to put the newly-created elements.
Choose elems to solid/surf comp to organize
elements in the same component that contains the solid and its
surfaces.
Choose elems to current comp to organize new
elements in the current component.
To smooth the elements on the resulting face of the solid to improve the
resulting mesh quality, select the smooth dest
checkbox.
For along parameters, define the parameters required for the mesh along the
solid map.
This determines the number of elements along the depth of the mapping. If the
size or density is set to "0", the element size/density is calculated based
on the average element size of the source elements (elems to drag).
For along bias style, choose the type of biasing to use while creating nodes in
the along direction.
The biasing style works in conjunction with biasing intensity. If intensity
is "0", biasing is not applied.
In the intensity field, enter a biasing intensity.
Click mesh.
HyperWorks X displays the progress of the solid map meshing process in
the status bar. Upon completion, HyperWorks X
displays a report of the mesh quality. The element quality value reported is the
worst scaled Jacobian in the mesh. The scaled Jacobian's value may range from 0.0 to
1.0(best). An elem's scaled Jacobian is a ratio of the elem Jacobian over the
Jacobian of an ideal elem of the same configuration.
