Select the rectangle as the main body and cylinder as the body to subtract and click the green check mark.įigure 4: Subtracting the cylinder from the prism
Select subtract and expand the "Solid Bodies" tab in the feature tree. Make sure that you uncheck "Merge Result" under the "Direction 1" tab. Extrude the square to make a rectangular prism, leaving plenty of space between the faces of the prism and the cylinder as shown in Figure 3.Next Create a large square in the right plane that will completely encompass the cylinder, leaving plenty of room on the sides as shown in Figure 2.įigure 2: A square large enough to fit around the cylinder.Create a 1m diameter cylinder in the front plane with a length of 1m, shown in Figure 1.įigure 1: The cylinder we will be simulating flow over.Open SOLIDWORKS and create a new part file.Since this tutorial is not about SOLIDWORKS but CFD, I'll go quickly over creating the model that will be used in the first simulation.
#ANSYS CFX TUTORIAL HOW TO#
If you have not done any of these, please check out the respective link(s) below:ĪNSYS Setup ¶ Simulation 1: Flow Over a Cylinder ¶ Creating a Model with SOLIDWORKSĪgain, I assuming that you have basic knowledge of how to use SOLIDWORKS to make this first model. This tutorial requires a little bit of background knowledge please make sure that you are familiar with basic aerodynamic principles, have basic SOLIDWORKS training, and have installed ANSYS on your system. If you are stuck, please reach out to an airframe director or project lead for assistance. It is recommended to split up the work over a few days. The time estimate for this tutorial is 2-2.5 hours, but it could take longer. ANSYS also has fluent fluid flow modelling, but CFX is better for aerodynamic properties so that is what we will focus on and use throughout our design process. In this tutorial we will learn how to simulate flows over bodies using ANSYS CFX fluid modeling.
