An automated study of the effect of geomteric and flow parameters on the laminar flow past a backward facing step is demonstrated in this tutorial. The step height, channel height and the inlet flow velocity are varied. The automation is achieved by controlling all analysis tools from one central application: Simulation Manager. It executes a simulation recipe that contains all the steps as a Python script. This tutorial will introduce the user to predefined simulation templates available in Simulation Manager. However, users can define their own scripts to modify geometry, gridding, volume conditions (VC), boundary conditions (BC), create custom GUI, conduct parametric and optimization studies.

The purpose of this tutorial is to show how to setup and post-process a parametric study involving geometric parameters. The example used for this tutorial is the case of a finned heat exchanger in which the fin thickness will be varied. The goal is to determine the fin thickness that result in the lowest temperature on the model.

This tutorial also shows how CFD-CADalyzer can be interfaced with CAD packages such as Autodesk Inventor, IronCAD, SolidEdge, SolidWorks, or ProE.

 

An automated parametric study of oil flow through a compliant orifice is presented in this tutorial. Based on a table of input values, Simulation Manager calls CFD-GEOM to update model geometry and grid, then runs the CFD-ACE+ solver for each case. The radius R of the compliant orifice is varied.

Model dependencies can be used to simulate complex rigid body motions. In this example, a pitching airfoil with flap is  used to demonstrate this feature.
A 2D axisymmetric RF CCP in Argon is modeled in this tutorial. 

The 1D positive column electron kinetic model is simulated through CFD-ACE+.  In the positive column, plasma can be assumed to be axially uniform. Therefore a 1D model can be used. An Ar + Hg mixture with simplified 6-step chemistry is modeled.

 
The simulation results of a 2D-axisymmetric flow of engine oil through a compliant orifice is post-processed through CFD-VIEW. The effects of thermal stress and fluid-structural coupling were included in this simulation.
 
This tutorial analyzes the case of an anisotropic elliptical plate under a constant pressure loading. This model is compared with an analytical expression for the vertical (z-direction) displacement provided by Timoshenko and Woinowsky-Krieger.
