CFD Lesson 2: SOLIDWORKS and 3DEXPERIENCE Fluid Scenario Creation (Part 2)

  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).

Dassault Systèmes owns SOLIDWORKS and various simulation software packages. Simulation packages range from SOLIDWORKS Simulation, CATIA Analysis, Abaqus and many others. All of them are under the SIMULIA family.

In the previous CFD Lesson 1:SOLIDWORKS and 3DEXPERIENCE Fluid Scenario Creation Part 1, we opened a SOLIDWORKS assembly that had not been saved to the 3DEXPERIENCE platform. Uploaded the assembly and saved it to a Collaborative space using an existing Bookmark.

Launched the Fluid Scenario Creation App and created an internal flow simulation that modeled the mechanical forces and dynamics of steady state fluid flow. Defined a fluid region internal to the model, specified the physics of the flow, and created a hex-dominant mesh for the fluid region.

We applied boundary conditions (inlet/outlet) and created output requests to collect pressure, flow velocity, and mass flow results.

Finally, we ran the Simulation study. Lesson 1 introduced the Physics Results Explorer App. We saved the Physics Simulation study to a Collaborative space on the 3DEXPERIENCE platform.

In this lesson, open a SOLIDWORKS session. Connect to the 3DEXPERIENCE platform. Utilize the 3DSpace widget from the MySession panel in the SOLIDWORKS Task Pane.

Your 3DEXPERIENCE | 3DDashboard is displayed. Locate the Physics Simulation study named, Ball valve in the saved Collaborative space. Use the sort by last or search method.

Launch the Fluid Scenario Creation App. Open the Ball valve Physics Simulation study. View the last displayed contour plot. Explore Help options. Create a section cut. Add streamlines to illustrate flow through the valve.

Save the Physics Simulation study. Close the study. Close the SOLIDWORKS session.

 

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. You should have a basic understanding of flow, pressure, velocity and the Computational Fluid Dynamics (CFD) method.

Before you begin this lesson, complete CFD Lesson 1: SOLIDWORKS and 3DEXPERIENCE Fluid Scenario Creation (Part 1).

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.

Log into the 3DEXPERIENCE platform.

Your 3DEXPERIENCE | 3DDashboard is displayed.

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.

Search for the Ball valve Physical Simulation

Note: You can also use the Search method. Search for the Ball valve (Physics Simulation) not the Physical Product.

Right-click Ball valve (Physics Simulation) as illustrated in the Title column below. A Pop-up menu is displayed.

Expand Open With. View your options.

Fluid Scenario Creation App

Launch the Fluid Scenario Creation App. Click the More Apps icon.

Click the Fluid Scenario Creation App.

This can take 15 – 20 seconds.

Click Restore if needed.

3DEXPERIENCE | SIMULIA Fluid Scenario is displayed.

Center the model if needed.

Review the Results: Pressure and Velocity

Expand the Result folder.

Display the last contour plot from CFD Lesson 1 Part 1.

Double-click the Result folder. The Physics Results Apps is displayed.

The last Simulation study contour plot is displayed.

Explore the Help options.

Click the Question mark icon as illustrated.

Display the Gauge Pressure.1 contour plot.

The inlet exhibits a higher pressure than the outlet.

View the Legend dialog box for the contour plot.

Double-click the contour plot as illustrated. View the Legend dialog box and options.

Close the Legend dialog box. Click Close.

 

The mouse cursor automatically acts as a probe.

Click a point on the model as illustrated. View the Gauge Pressure at that point. A Pop-up menu is displayed. Note: to deselect the displayed point, click in the Graphics area.

Click the Plot sectioning icon in the Pop-up menu. By default, the app creates a cutting surface at the center of the model. The normal to the plane is oriented in the global Z-direction.

View your options.

 

 

Show section and behind cut, Show section and in front of cut, Show section, Show behind cut, Show in front of cut, Show section, behind and front of cut.

Show/Hide cutting geometry and robot manipulator.

Edit cut.

Create cut surface.

 

Deactivate cut.

Click OK.

View the results in the Graphics area.

 

 

Display the Velocity Vector.1 contour plot. View the flow velocity in vector format.

The velocity is lowest along the boundary layer and in the corners of the inlet and outlet of the valve. It’s the highest at the restricting internal ball of the valve.

Display Streamlines

Add streamlines to illustrate the flow through the valve. Streamlines create a family of curves that are tangential to the velocity vector of the flow and show the direction of particle travel at any point in time.

Create an automatic stream. Use the defaults to define the scope and density. The scope definition tells Physics Results Explorer to display streamlines for the whole model or for the current display group only. The density is the number of streamlines across the inlet.

Display the Assistant dialog box.

Click Results.

Click Streamlines.

 

 

View the results. The streamlines display the flow path from the inlet to the outlet. Airflow is laminar at the inlet but becomes mixed as it passes through the valve and Control Ball. This turbulence is a result of abrupt turns in the valve setting.

Note: The Control Ball is set at 165 degrees from the Front Plane of the assembly.

Explore the Pop-up menu.

Click OK.

Below is an illustration of Gauge Pressure.1 with Streamlines.

Save and Close

Save the Physics Simulation study (Model, Scenario and Result).

Click the Share icon as illustrated.

Click Save.

 

 

Close the Physics Simulation study.

Click Close on the Ball valve A tab.

Return to the active SOLIDWORKS session.

Close your SOLIDWORKS Session.

The lesson is finished.

In CFD Lesson 3 Part 3, start a SOLIDWORKS session. Open the SOLIDWORKS part from CFD Lesson 2 (Part 2).

Launch the 3DSpace Widget from the SOLIDWORKS Task Pane.

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.
