ACU-T: 5001 Blower - Transient (Sliding Mesh)
Prerequisites
This tutorial provides the instructions for setting up, solving and viewing results for a transient simulation of a centrifugal air blower utilizing the sliding mesh approach. In order to run this tutorial, you should have already run through ACU-T: 5000 Blower - Steady (Rotating Frame) and kept the solution in your working directory. It is assumed that you have some familiarity with HyperMesh, AcuSolve, and HyperView.
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 ACU-T5001_BlowerTransient.hm from HyperMesh_tutorial_inputs.zip.
Since the HyperMesh database (.hm file) contains meshed geometry, this tutorial does not include steps related to geometry import and mesh generation.
Problem Description
Open the HyperMesh Model Database
Run the Steady State Simulation

Create Mesh Motion
Modify the Boundary Conditions
Specify the Nodal Initial Conditions
Compute the Solution
Post-Process the Results with HyperView
Open HyperView and Load the Model and Results
Create a Pressure Animation
Create Streamlines
Summary
In this tutorial, you successfully learned how to set up and solve a transient simulation of a centrifugal air blower using the sliding mesh approach. You started by importing the meshed geometry and then ran the steady state simulation. Then, you used the steady state result as the starting point for the transient simulation using the AcuProj tool to specify the nodal initial conditions and then solved the transient simulation using the sliding mesh approach instead of the moving reference frame approach. Once the transient solution was computed, you launched HyperView and created an animation of pressure contours and streamlines.
