HWCFD-T: 0001 Introduction to HyperWorks CFD User Interface
- Menu bar
- Ribbons
- Modeling window
- Entity selector
- View Controls toolbar
- Browsers
- The menu bar (1) contains the drop-down menus for File input-output, Edit, and View operations.
- Ribbons (2) contain various functionalities and tools
available in HW-CFD. Navigate between various ribbons by clicking the ribbon tabs to
the right of the menu bar. After selecting a ribbon, the
corresponding tool icons are displayed on the screen. The functionalities of various
ribbons and corresponding tools are briefly explained in this section.
- Geometry ribbon
-
The Geometry ribbon consists of tools for converting, repairing, creating, editing, and validating the geometry. The tools available under the FE Geometry sub-section can be used to convert a geometry model to an FE model, cap the openings automatically, define local or proximity-based wrap controls, wrap the model, remesh the wrapped results, and fix the mesh quality.When a geometry file is imported, the Repair tools can be used to detect any defects present in the CAD model like intersections, free edges, duplicates, sliver surfaces, etc. and fix those errors.The tools available under the Create sub-section can be used to create geometric entities like points, lines, surfaces, etc.The tools required for performing operations like plugging cavities, stitching surfaces, etc. are available under the Edit sub-section.The Defeature tool can be used to resolve these defects or model a new geometry, while the Validate tool can be used to detect any defects present in the CAD model. This process is usually known as CAD cleanup.
- Flow ribbon
-
The Flow ribbon contains tools for setting up simulation parameters, solver settings, and reference properties such as material properties, heat sources, porous media, etc. The Setup sub-section is where you set up the physics equations and solver settings as well as create material models, multiplier functions, and parameters.The Domain sub-section contains tools for assigning reference properties such as materials, heat and momentum sources, reference frames, etc. to volumes.Surface boundary conditions such as inlets, outlets, far fields, etc. can be assigned using the tools under the Boundaries sub-section. By default, all the surfaces are assigned a boundary condition of type ‘auto_wall’ and are placed under Default wall. Please refer to the AcuSolve Surface Processing manual for more information about auto_wall. As you assign boundary conditions to the surfaces, they are moved into the respective group.
- Radiation ribbon
-
The Radiation ribbon is where you define radiation physics, create thermal, solar, and participating media models, and apply radiation parameters.
- Motion ribbon
-
Mesh boundary conditions and mesh-motion-related parameters can be defined using the tools available in the Motion ribbon. Parameters such as mesh motion type and mesh displacement constraints can be defined here.
- Mesh ribbon
-
Meshing parameters such as surface mesh controls, boundary layer parameters, volume mesh parameters, and zone meshing parameters can be defined here. This ribbon also has tools for local remeshing. Once all the mesh controls are defined, you can generate the mesh using the Batch tool.
- Solution ribbon
-
The Solution ribbon is used to set up monitors for any individual point, surface, or volume set output. The Field tool is used to set the nodal output frequency for the entire model. The Initialize tools are used to set the nodal initial conditions for variables like pressure, velocity, and variables specific to each turbulence model.
Once the complete set up is done, the Run tool is used to launch AcuSolve. Once the AcuSolve run parameters are set, the simulation can be started, and you can monitor the status of the run using the run manager.
- The modeling window (3) is where the
model is displayed. The model display can be manipulated using the view controls
shown in the table below. Clicking on the model will highlight the entity being
selected and right-clicking on an entity will give you additional options for the
operations that can be done based on the context. Some of the functions available
using right-click are Show, Hide, Isolate, Select, Advanced select, Create groups,
etc.
Button Operation Middle mouse scroll Zoom in and out Right-click hold and drag Pan the model Middle mouse click hold and drag Rotate the model Left-click Select entity Ctrl + Left-click Select multiple entities Left-click hold and drag Window select Shift + Left-click Deselect entities - The entity selector (4) enables you to control what entities can be selected using the left-mouse button. The selector can be set to any of the entities shown in the figure below. When you open any tool, the selector is automatically set to the entity (entities) which are appropriate for that command.
- The visualization of the model can be controlled using the tools available in View Controls toolbar (5). The display of mesh, model display mode (e.g. Topology, part, assembly, etc.), section cuts, standard views, etc. can be controlled using these tools.
- The Part Browser and Setup Browser (6) show all the entities and setup parameters in the model and list them in a tree structure. Both can be turned on or off from the View menu. Some common functions that can be performed in the both browsers are show, hide, and isolate. The Part Browser can be used to manage the model's parts, surface bodies, and solid bodies while the Setup Browser can be used to create and edit instances of model setup parameters such as boundary conditions, domains, mesh controls, etc.
Starting from ACU-T: 1000, the tutorials in the guide use Altair HyperView for post-processing the results. For detailed information about the user interface of HyperView, please refer to Introduction to HyperView.
