Browsers in HyperMesh
The browsers can be opened in the View > Browsers. Browsers display information in a tree view. In tree views, collectors such as components or groups appear at the top level of the hierarchy, while collected entities such as elements or surfaces display as "children" nested within the collector to which they belong. Each item in a tree view is commonly referred to as a "node", regardless of whether it is a Parent Node or a Child Node.
Performing an action on a child node affects only that item, be it a single load or the entire collection of elements in the model (which, in the example above, are collectively a child node of the components parent node). However, performing the same action on a parent node applies it to all children of that node as well. For example, in the image above, turning off the display of elements will not affect the display of connectors, geometry, or components (the parent node of the elements). However, turning off the display of components will turn off the display of connectors, elements, and geometry because they are children of the components node. Different browsers are customized for usage with regard to the types of parts that you want to work with. Most browsers have similar basic functionality for sorting entities, filtering entities, and finding entities. However, most browsers also include a right-click context menu and sets of control buttons (similar to toolbars, but unable to be detached to re-docked) that are specific to the browser in which they appear.
A context menu of actions is available for any selected item in the browser. To open the context menu, right-click on either an entity folder, an individual entity, or the white-space of the browser.
The Model Browser resides on a tab in a Tab Area sidebar and allows you to view the HyperMesh model structure while providing full find, display, and editing control of entities. The model structure is viewed as a flat, listed tree structure within the browser. However, if the model has an assembly hierarchy then the Model Browser accommodates this hierarchical structure. The browser can list every named entity within the HyperMesh session and places those entities into their respective folders; however, it does not support non-named entities such as nodes and elements. Some of the more important entities within the model include: assemblies, components, multibodies, properties, materials, entity sets, groups, load collectors, system collectors, vector collectors, and beamsectcols--all of which are placed into a tree-like display.
Mouse over the areas of the Model Browser to see a description of the options.
Use the Entity Editor to quickly view and edit entities in a model and correctly setup solver information. The Entity Editor can be accessed from the Model, Reference, and Solver browsers. In the Model browser, the following view modes are supported: Model, Include, Component, Property, and Material. When accessing the Entity Editor from the Reference browser, you will only be able to view your entity selection's corresponding data in a non-editable form.
The Entity Editor opens when you create new entities, as well as duplicate, edit, or select single or multiple entities in the browser. To expand and collapse the Entity Editor, click ee_collapse_expand in the top, right-hand corner. To adjust the height of the Entity Editor, drag sash_ee up and down.
Entity parameters are displayed in the Name column, and the values associated with each parameter are displayed in the Value column. The parameters that display in gray text, cannot be edited. Once you edit an entity in the Entity Editor, the changes will be automatically applied throughout your model.
In the Mask browser, set the mask/unmask state for entities at the entity configuration level. An example of the Mask browser is shown below.
The entities are logically organized in the browser to represent the collectors they belong to. Regardless of the current model, the entities listed in the browser remain the same. The Show/Hide/Isolate columns contain icons that can be clicked to perform the relevant masking operations. The buttons perform the masking operations at the selected entity and folder level, and for all entities and sub-folders that may be contained within that folder. These operations are only valid for entities contained in collectors that are currently displayed.
The Show column corresponds to the unmask operation. It unmasks the relevant entities for the current row and sub-folders. For example, the Show icon at the Geometry folder unmasks all points, lines, surfaces and solids within any displayed components.
The Hide column corresponds to the mask operation. It masks the relevant entities for the current row and sub-folders. For example, the Hide icon at the 1D folder masks all rod, bar2, bar3, weld, joint and plot elements within any displayed components.
The Isolate column corresponds to both a mask and an unmask operation. It performs a Hide on the top level folder and then a Show on the current row and sub-folders. For example, the Isolate icon at the 3D folder masks all connectors, geometry, 0D/rigid elements, spring/gap elements, 1D elements and 2D elements and unmasks all 3D elements within any displayed components. The exception to this rule is when the Isolate button is selected at a top-level folder; in this case, all sub-folders underneath the top-level folder are unmasked and all other top-level folders (and their contents) are masked. For example, the Isolate icon at the Components folder masks all supported entities in any displayed groups, load collectors, morphing, multibodies and system collectors--and unmasks all supported entities within any displayed components.
The Mask browser's context menu contains functionality unique to the browser.
The Solver browser provides a solver perspective view of the model structure in flat, listed tree structure. Hierarchical structures are only available for card images that allow variations with themselves. For example, the MAT card image has several different material types and each material has its own entity defined in HyperMesh, so a hierarchical structure is used to list them all.
The Solver browser lists every entity mapped to a solver card image within the session and places those entities into their respective solver card image folders. The total number of entities is displayed in parenthesis next to the entity name. To display every entity type supported by the solver in the browser, go to the Browser Configuration dialog, Local Options, and select Show empty folders.
In the LS-DYNA user profile, the Solver browser supports two view modes: Solver and Include Solver view. Switch between the two view modes by clicking their respective icons in the top, left corner of the browser.
In the Include Solver view, data is organized into Include files. Data which does not have any references to an Include file is stored in the master model.
