Solid Map Panel

Location: 3D page

Only relatively simple solids can be meshed; complex objects must first be partitioned into simpler sections so that the sections can be meshed individually.

Furthermore, even if all solids are mappable, they may not all be meshable at once; you may still need to mesh each mappable solid individually, or only a few at a time. Any given volume can have one of four states, which are color-coded when using the mappable view option on the Visualization toolbar. Although the colors can be customized, the default settings are:

Blue: A solid that has not been edited at all, and therefore is not evaluated for mappability.
Orange: A solid that has been edited, but remains completely unmappable (further partitioning may enable mapping).
Yellow: A solid that is mappable in one direction.
Green: A solid that is mappable in three directions (this is very rare).

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. To use other mesh quality measures, go to the Check Elements panel.

Note: All of these subpanels depend on an existing 2D mesh, which is then extrapolated into a 3D mesh based on the parameters you input. The One Volume and Multi Solids subpanels, however, can automatically create 3D mesh directly on solids as long as the solids you select are already mappable.

You can omit the source, the destination, or the along geometry by setting either one of the entity selectors to (none). Only one of these selections can be set to (none); the other two selections are then required to define the volume to fill.

The 2D meshes extruded do not have to be continuous.

The "along" faces do not all have to be defined.

You can create elements with a user-specified bias by selecting linear, exponential, or bellcurve after bias style. Specify the bias intensity value after intensity = and click mesh.

General Subpanel

Use the General subpanel to access all of the possible entry controls for maximum flexibility.

Option	Action
source geom	Choose a method for selecting source geometry that defines the source face of the 3D volume. surfs Select surfaces that define the source face of the volume/solid. lines Select lines that define the periphery of the source face. nodes Select multiple lists of nodes, each representing the periphery of the source face. none No source geometry is defined. The geometry inferred from the elems to drag is considered as source geometry.
elems to drag	Select the elements/mesh that correspond to the source face extruded to create the solid mesh. If the source face type chosen is a surface, the elements to drag selection is optional as the elements associated to the surface are automatically selected.
dest geom	Choose a method for selecting the geometry that defines the destination face of the 3D volume. surfs Select surfaces that define the destination face of the volume/solid. lines Select lines that define the periphery of the source face. nodes Select multiple lists of nodes, each representing the periphery of the source face.
elems to match / smooth dest	elems to match Select the elements on the destination surface that you wish the 3D mesh to match up with. smooth dest Smooth the mesh that is mapped on the destination face when your destination geometry varies greatly from the source geometry.
along parameters	Define/set the parameters required for the mesh along the solid map. Set the element size or density (toggle) to be defined in the along direction. 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).
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 set to "0" the biasing is not applied.
intensity	Specify the biasing intensity value.

Line Drag Subpanel

Use the Line Drag subpanel to select a 2D mesh, and then select a line from the model geometry to use as the mapping direction.

Option	Action
elems to drag	Select the elements/mesh that correspond to the source face extruded to create the solid mesh. If the source face type chosen is a surface, the elements to drag selection is optional as the elements associated to the surface are automatically selected.
elems to match / smooth dest	elems to match Select the elements on the destination surface that you wish the 3D mesh to match up with. smooth dest Smooth the mesh that is mapped on the destination face when your destination geometry varies greatly from the source geometry.
along geom	Choose a method for selecting the geometry that defines the face of the 3D volume along which you wish to map the mesh. surfs Select surfaces to define the mapping face of the volume/solid. lines Select lines that define the periphery of the source face. nodes Select a node list that defines a line along which to map. mixed Select any combination of surfaces, lines, 2D elements/shell faces, and/or nodelist/nodepath. When elements are used, the mapped solid mesh maintains the nodal positions with selected elements. They can be equivalenced to have common nodes. While selecting nodelist/nodepath, each selection should represent an edge that connects the source and destination.
along parameters	Define/set the parameters required for the mesh along the solid map. Set the element size or density (toggle) to be defined in the along direction. 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).
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 set to "0" the biasing is not applied.

Multi Solids Subpanel

Use the Multi Solids subpanel to select multiple mappable solids and create 3D meshes for them.

HyperWorks X can create volume meshes on multiple shapes at the same time, allowing you to mesh solid parts faster.

Note: Complex parts must still be partitioned into multiple simpler solids.

This does not always work for large numbers of solids, even if they are all mappable. In some cases you may need to mesh them a few at a time or even (in extreme cases) individually.

Clicking mesh in this panel will create the solid mesh if automatic mode had been selected. If the interactive mode was selected, it will create any temporary 2D shell meshes required and assign the node seeding density to all of the along edges. Then it will open the Density subpanel.

Option	Action
solid	Select the desired solids. Note: Only solids that are mappable can be meshed.
interactive / automatic	automatic Create the 3D solid mesh immediately. interactive Use the subpanels to enable further control over the mesh density and element mesh patterns.
elem size	Specify the size to when initially distributing the nodes to the edges.
source shells	Select the type of source shells that define the 2D mesh on the initial surface of the solid, and will dictate the output element type when meshing the solids. mixed Create hexa and penta elements. quad Create only hexa elements. trias or R-trias Create only penta elements (right-angle pentas in the case of R-trias).
source hint	Select the "beginning" surface that defines the direction of mesh mapping.
dest hint	Select the "ending" surface that defines the direction of mesh mapping.
elems to solid/surf comp / elems to current comp	Select which component to put the newly-created elements. elems to solid/surf comp Add the elements to the same component that contains the solid and its surfaces. elems to current comp Add the new elements to the current component.
smooth dest	Smooth the elements on the resulting face of the solid to improve the resulting mesh quality.
apply orthogonality to along	Keep the solid elements generated more perpendicular to the surface faces in the along direction.
stop meshing on bad jacobian	Halt the meshing routines upon the creation of a bad jacobian solid element.
previous settings	When creating the temporary surface mesh, honor any prior edge node density settings.

Command Buttons

Option	Action
mesh	Create a solid mesh with all the provided input. The solid mesh created is placed in a collector named solidmap. If that collector does not exist, a new component is created with that name.
reject	Reject the last mapped solid mesh created.
equiv/faces	Equivalence all of the elements in the solidmap component and create the faces (^faces component) for that component. This function is optional and does not directly impact the solidmap functionality. It allows you to perform faster and easier solid modeling. The solidmap component is equivalenced with an initial tolerance of 1% of element size. When this function is performed, a message is displayed informing you of the number of nodes equivalenced along with the tolerance value used. Any subsequent use of this function without performing additional solid mapping increases the tolerance (to a maximum of 10% element size) before equivalencing again.
return	Exit the panel.
