HWCFD-T: 0001 Introduction to HyperWorks CFD User Interface

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.

Figure 3.

The tools available under the Create sub-section can be used to create geometric entities like points, lines, surfaces, etc.

Figure 4.

The tools required for performing operations like plugging cavities, stitching surfaces, etc. are available under the Edit sub-section.

Figure 5.

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.

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.

Figure 7.

The Domain sub-section contains tools for assigning reference properties such as materials, heat and momentum sources, reference frames, etc. to volumes.

Figure 8.

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.

Figure 9.

The Radiation ribbon is where you define radiation physics, create thermal, solar, and participating media models, and apply radiation parameters.

Figure 10.

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. In addition to the mesh boundary conditions, code coupling with external codes such as OptiStruct and MotionSolve can be defined here

Figure 11.

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 Volume tool.

Figure 12.

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.
