Solidworks Tutorial: Beginner Flow Simulation Tutorial

Introduction Solidworks has built in computational flow dynamics capabilities that are very useful for determining the

effect of fluid flow on a solid model. However, these functions can be complicated and confusing to use.

This tutorial is intended to give basic instruction on how to setup and run a basic flow analysis. This is

not intended to be a comprehensive flow simulation instruction, but it is a good place to start.

Tutorial

1) Open Solidworks

2) Open Part - Pressure Vessel

3) Make assembly from part

4) Solidworks will require a closed system to be analyzed. In this

step we will close the geometry on the system by adding lids to the

pipes.

a) Click the arrow below Insert Components and select New Part

b) Using Sketch and Features tools, create a lid for each pipe.

c) Complete editing by clicking on Edit Component in tool bar.

5) Open FloXpress

Note: FloXpress will not work if the Flow Simulation add-in is currently installed. If it is

installed, click on Tools > Add-Ins and uncheck the box next to Solidworks Flow Simulation.

a) Save model

Note: In order to run FloXpress, Solidworks requires that the current model be saved. Saving the

model to a local directory rather than a network directory will increase the speed of the FloXpress

solution.

Note: When the Save As box pops, choose to Save Internally. This will save the lids inside the

current assembly file and eliminate the need for individual lid files.

b) Create a section view of the part

Note: This step is not required, but makes setting parameters and analyzing the output much

easier.

c) Open FloXpress by clicking Tools > FloXpress

6) Navigate FloXpress

a) Once FloXpress has been opened a new

dialog box appears where your Part Tree is.

b) Use the blue arrow button in the top of the dialog box to

navigate the parameters and set your fluid inlet and outlet.

Note: Do not use the enter key when inputting parameters as this will close out the dialog box

and you will need to reopen it.

7) Once FloXpress has solved your model, we are limited to

analyzing the velocity of fluid streams. In order to exploit the full

power of Solidworks it is necessary to open these definitions using

the Solidworks Flow Simulation add-in.

a) Display fluid velocities.

Note: Fluid paths can be displayed as either pipes, similar to a vector, or a ball, similar to a fluid

particle. A fluid velocity will be denoted by a color variation in these pipes or balls.

b) Animate the flow.

Note: Animations can also be created by clicking the play

button under Velocity Plot.

This will show a basic animation of the fluid path and mixing

involved in the process.
