Introduction to AcuSolve Tutorials
This guide contains a collection of simulation cases with explicit instructions for setting up, solving and post-processing. A range of tutorials are included to illustrate the basic AcuSolve workflow and to provide guidance for setting up a variety of problems.
Some tutorials can be completed with a choice of pre-processor. Therefore, two sets of tutorials are provided here: one for HyperMesh CFD and one for SimLab.
Objectives
- Present the basic AcuSolve workflow.
- Introduce the capabilities of AcuSolve to new users.
- Provide guidance for the use of AcuSolve with industrial applications.
Prerequisites
No experience with AcuSolve is needed prior to running through the tutorials included in this guide. It is expected that you have some exposure to basic principles of engineering and computer-aided engineering.
For the HyperMesh CFD based tutorials, it is strongly recommended that you go through the introductory tutorial ACU-T: 1000 UI Introduction before proceeding to the other tutorials. This tutorial includes the steps to import the geometry model, define surface mesh controls and boundary layer parameters, and so on, which are not included in the subsequent tutorials. For these remaining tutorials, you will be provided a HyperMesh database (.hm file) which has the pre-defined mesh controls. Instructions related to post-processing have been included in all the tutorials.
For the SimLab based tutorials, it is recommended that you go through the introductory tutorial ACU-T: 1000 UI Introduction before proceeding to the other tutorials. This tutorial provides an overview of the panels, ribbons, and toolbars in the SimLab user interface followed by demonstration of the CFD workflow. All the SimLab tutorials start from importing the CAD geometry, generating mesh, and setting up the simulation to post-processing the results. All the tutorials are video-based and you need to have an internet connection to view the videos and to download the files.
Basic Workflow
HyperMesh CFD Based Tutorials
- Problem description
- Start HyperMesh CFD and open the HyperMesh database
- Validate the model
- Set up the simulation parameters and solver settings
- Assign material properties to the fluid and solid regions
- Define any porous media, body force, and/or reference frames
- Assign flow boundary conditions, such as inlet, outlet, slip, symmetry, and so on
- Define any radiation parameters
- Define any mesh motion and mesh boundary conditions
- Define surface mesh controls, boundary layer and volume mesh controls, and generate the mesh
- Define nodal output frequencies, surface and volume monitors, and nodal initial conditions
- Compute the solution using AcuSolve
- Post-process results with the plot utility (to visualize data related to the progress of the calculations) and/or with HyperView to visualize simulation data with contours, vectors, streamlines, and the like
