Solidworks Flow and static analysis

SOLIDWORKS versatility is extensively demonstrated on the nature of simulations studies it can do. One very important feature we love about SOLIDWORKS Simulation is its capability to run a combination of simulations.

SOLIDWORKS allows users to import the results of say a flow simulation into a static study. Not only that but it allows us to run several simulations concurrently depending on the designer’s needs.

For this example, we will be going over how we can conduct a flow simulation, then based on the results run a subsequent static study. Let’s begin by creating the pipe network as shown.


Before we setup the Flow Simulation, we need to first create lids for the ends. Lids can only be generated when the Flow Simulation add-in is enabled.

Once we have created the lids, we can create a section view to better visualize the flow. Proceed to run the flow simulation wizard.

Choose a name for the study and select the units that are to be used in this study.


In the analysis type choose internal analysis as the fluid will be flowing inside the pipe. Be sure to indicate the liquid as water for this study.


SOLIDWORKS Flow Simulation automatically sets up the fluid domain, and of course it can be changed but it may have an effect in meshing. We can proceed by first defining the boundary conditions. Set the inlet mass flow rate at 5kg/s.




Set the outlet conditions as environmental pressure.

Once you have defined your boundary conditions you can then proceed to run the flow simulation. You can do a flow trajectory plot to visualize the flow field.


Create a new static simulation study. In the study exclude the lids from the analysis.


Setup the fixed geometry which in our case will be the ends of the pipe network.


Right click on the external loads and select flow effects. Choose to include pressure due to flow through the network then browse for the file 1.fld.

Define the material for your part then run the analysis.


From the results, we can observe how the pipe deforms due to the pressure of fluid flowing through the network.
