ACU-T: 1000 HyperWorks UI IntroductionHyperMesh

This tutorial provides the instructions for setting up a Computational Fluid Dynamics (CFD) simulation making use of the HyperWorks package. HyperWorks is a comprehensive suite of various Computer-Aided Engineering (CAE) products, each specialized in a certain aspect of the CAE process. These include HyperMesh as a generic, powerful geometric modeling and pre-processing tool, and HyperView as a post-processing and visualization tool. Bridging these two applications is a complete range of solvers for a gamut of engineering applications. Among these solvers is AcuSolve, which is Altair’s offering for fluid flow and thermal analysis simulations.

HyperMesh’s inbuilt geometric modeling and finite element meshing capabilities will allow you to create the geometry for your problem and generate excellent quality meshes in a single tool. Meshes generated in HyperMesh can be exported in the format that AcuSolve will recognize. Moreover, HyperMesh’s integration with AcuSolve also allows you to complete the pre-processing steps in HyperMesh itself, including the problem setup. Once you have completed setting up your simulation in HyperMesh, you can directly generate the AcuSolve input files. You can also choose to directly launch AcuSolve from within HyperMesh. This integration is expected to be especially beneficial for you if you happen to be a traditional user of HyperMesh for your modeling and meshing requirements.

The HyperWorks package has a powerful tool for post-processing and visualizing the results of your CFD simulations, called HyperView. HyperView enables you to visualize data interactively as well as capture and standardize your post-processing activities using process automation features. HyperView combines advanced animation and XY plotting features with window synching to enhance results visualization. HyperView also saves 3D animation results in Altair's compact H3D format so you can visualize and share CAE results within a 3D web environment using HyperView Player. HyperView has a rich feature set that you might find beneficial to your post-processing activities and are useful to explore. HyperView has inbuilt direct-reading capabilities for AcuSolve results and does not require any conversion steps.

In this tutorial, you will learn how to use HyperMesh for importing a geometric model and generating a mesh. You will then set up and launch the simulation from within HyperMesh. Following that, you will learn how to use HyperView for post-processing AcuSolve results.

In this tutorial you will do the following:
  • Analyze the problem
  • Start HyperMesh and create a model database
  • Import the geometry for the simulation
  • Generate and organize the mesh using the Mesh Controls Browser
  • Set general problem parameters
  • Set solution strategy parameters
  • Set the appropriate boundary conditions
  • Run AcuSolve
  • Monitor the solution with AcuProbe
  • Post-process with HyperView

Prerequisites

To run this simulation, you will need access to a licensed version of HyperMesh and AcuSolve. This tutorial introduces you to HyperMesh and HyperView so no prior experience is expected.

Prior to running through this tutorial, copy HyperMesh_tutorial_inputs.zip from <Altair_installation_directory>\hwcfdsolvers\acusolve\win64\model_files\tutorials\AcuSolve to a local directory. Extract from HyperMesh_tutorial_inputs.zip.

The file stores the geometry information for the fluid portion of the model for this problem in Parasolid ASCII format.

The color of objects shown in the modeling window in this tutorial and those displayed on your screen may differ. The default color scheme in HyperMesh is "random," in which colors are randomly assigned to groups as they are created. In addition, this tutorial was developed on Windows. If you are running this tutorial on a different operating system, you may notice a slight difference between the images displayed on your screen and the images shown in the tutorial.
