# CFD Lesson 3: SOLIDWORKS and 3DEXPERIENCE Fluid Scenario Creation (Part 3)

After teaching 1000’s of students and writing about SOLIDWORKS for over 25 years, David Planchard, emeritus WPI, is exploring SOLIDWORKS desktop and the integrated 3DEXPERIENCE Platform.  Through the 3DEXPERIENCE Works Lesson series, David helps educators understand the 3DEXPERIENCE Engineer, Fluid Scenario Creation App (CFD) with simple examples and industry practices. The Platform offers are available thru your Education Partner (VAR).

In CFD Lesson 2 Part 2, we opened a SOLIDWORKS session. Connected to the 3DEXPERIENCE platform. Utilized the 3DSpace widget from the MySession panel in the SOLIDWORKS Task Pane. Located the Physics Simulation study named Ball valve in the saved Collaborative space. Used the sort by last method.

Launched the Fluid Scenario Creation App. Opened the Ball valve Physics Simulation study. Viewed the last displayed contour plot. Explored various Help options. Added streamlines to illustrate flow through the valve. Saved the Physics Simulation study. Closed the study. Closed the SOLIDWORKS session.

In this lesson, start a SOLIDWORKS session. Open the SOLIDWORKS part from CFD  Lesson 2 (Part 2). View the Status State, Revision and Maturity State in the Task Pane. Launch the 3DSpace Widget from the SOLIDWORKS Task Pane. View your Collaborative space. Locate the Physics Simulation study named Ball valve in the saved Collaborative space. Use the sort by last method.

Launch the Fluid Scenario Creation App. Return to the active SOLIDWORKS session. Modify the Ball valve control angle from 165 degrees to 145 degrees relative to the Front Plane. This will increase flow restriction and pressure drop.

Create a new revision (B). Save the new revision (B) to the My Work folder in the 3DEXPERIENCE vault. Load the new revision (B) into the Physics Simulation study on the 3DEXPERIENCE platform using the Collaborative Lifecycle App.

Link the Physics Simulation study with the new revision. Apply the Replace Model By Revision command. Link the Physics Simulation study to the new model revision. Run the Physics Simulation study. View the results.

Save the Physics Simulation study. Close the Physics Simulation study. Return to SOLIDWORKS.

Delete the Simulations study Ball valve (Physics Simulation and Finite Element) along with the assembly and reference components (Physical Products) in the 3DEXPERIENCE Platform. Use the 3DSpace Widget from the SOLIDWORKS Task Pane.

## Launch the 3DEXPERIENCE Platform and Start SOLIDWORKS

Before we start, there are a few items that you need to know.

In this lesson, use your default Collaborative space. An internet connection is required. A 3DEXPERIENCE ID is required.

The Flow Simulation lesson provides a foundation to users who are new to using simulation to solve real-world engineering and design problems. A Solid body is used. You should have a basic understanding of flow, pressure, velocity and the Computational Fluid Dynamics (CFD) method.

3DEXPERIENCE Launcher needs to be installed. 3DEXPERIENCE Works Lesson 1: Getting Started with SOLIDWORKS.

The 3DEXPERIENCE platform is browser driven. Your existing cookies and cache determine what you will see on your computer desktop or during a SOLIDWORKS login. A full installation of SOLIDWORKS 2019 SP0 or later is required.

Start a SOLIDWORKS session from your desktop.

Double-click the SOLIDWORKS icon.

View the illustration below. Depending on your system setup, cookies, and cache, it will be different. Read the provided information.

Input the requested data.

Click Accept All.

The Welcome – SOLIDWORKS dialog box is displayed.

You are logged into the 3DEXPERIENCE platform.

Close the Welcome dialog box.

Click the 3DEXPERIENCE icon in the Task Pane. The MySession panel is displayed. This displays the two-way communication between SOLIDWORKS running on your desktop and the 3DEXPERIENCE platform running in the cloud.

In this lesson, I’m using a Collaborative space named Quick Start xDesign.

Note: If you do not see the 3DEXPERIENCE icon, click the Options drop-down arrow, click Add-Ins, check the 3DEXPERIENCE box, click OK, from the SOLIDWORKS Main menu.

Click Accept All if needed.

## Open the Ball value assembly

Open the Ball valve assembly that was download, used in CFD Lesson 1 (Part 1) and saved at the end of the lesson. This Ball valve was previously uploaded and saved to the 3DEXPERIENCE platform.

Expand the Task Pane bar. The MySession panel displays the Component Name (Ball valve), Status (File is modified since the last time saved to the platform), Locked status (Locked), Rev (Revision A), Is Last Revision (Yes), Maturity State (In Work) and more.

The orange save Status icon for the Ball valve assembly and reference components informs you that the file was modified since the last save into the 3DEXPERIENCE platform.

Use the 3DSpace widget to view your Collaborative space, review 3DEXPERIENCE Works Lesson 5: SOLIDWORKS, Collaborative Space and Bookmarks. A widget is an extension of the App that allows you to use it in the Dashboard. A widget is displayed with an arrow in the upper right corner of the icon as illustrated.

Drag the slider downward to view the 3DSpace widget.

Click the 3DSpace widget. Note: The 3DSpace widget is used to create a Collaborative space. The default location defines the Collaborative space (cloud storage) where your models and data are saved.

Your 3DEXPERIENCE | 3DDashboard is displayed.

## Collaborative Space

In CFD Lesson 1 Part 1, I saved the Fluid Scenario Creation Simulation study (Model, Scenario and Result) in my Quick Start xDesign Collaborative space.

Double-click your Collaborative Space. In this example it is Quick Start xDesign.

Locate the Physics Simulation study (Ball valve). In this example, I use the sort by last method.

Click the Sort icon. A drop-down menu is displayed.

Select Modification date (31-1).

View the results.

## Fluid Scenario Creation App

Right-click Ball valve (Physics Simulation) as illustrated in the Title column below.

Enter 145 degrees.

Click OK.

Save the model to the My Work folder in the 3DEXPERIENCE vault. The default location on a non-network system, is C: 3DEXPERIENCE\My Work. Note: When you upload a file to the platform, the file is both copied to the My Work folder on your computer and stored in your collaborative space on the 3DEXPERIENCE platform. A collaborative space is a storage area that manages version control for shared files.
