Once we open up the check geometry tool, we can select all applicable parts that we wish to check, in this case, we will use all parts of this valve assembly. The check geometry option is found under the main Tools Menu > Flow Simulation > Check Geometry. If a model is not watertight, it is indicating that some portion of your model is exposed to the open fluid surrounding your part, and therefore, will need to be closed prior to beginning a Flow Simulation project. The first thing you should do for any SOLIDWORKS Flow Simulation project is to check the geometry for internal flow, this will determine if your model is watertight. Prior to doing that we need to prepare the model. Therefore, as we are solely concerned with the fluid flow on the interior of the valve, we need to set up an internal flow study within SOLIDWORKS Flow Simulation. For a butterfly valve, we want to monitor the fluid effect through the valve – not over the valve. In this part of our Flow Simulation tutorial, the first task for beginning a project is to determine what type of flow study you need to conduct.

How to prepare a butterfly valve for internal flow If you select the wrong study type it may prevent you from solving your problem or solving it efficiently. It is important to understand the two different study types in order to select the appropriate study for your problem. In this case, the fluid only circulates on the interior of your part, this type of analysis is most commonly associated with pipe or valve studies. Internal flow studies concern flow bounded by outer solid surfaces. In this case, the solid part is surrounded by the flow, this type of analysis is most commonly associated with aerodynamic studies. External flow studies concerns flows not bounded by outer surfaces, but rather only by the fluid domain boundaries. Within SOLIDWORKS Flow Simulation users have the ability to solve either external flow or internal flow studies. What are the two different study types in SOLIDWORKS Flow Simulation? SOLIDWORKS Flow Simulation shortens time to market by saving time and effort searching for the optimum design. Powered by fast and accurate solvers, SOLIDWORKS Flow Simulation enables you to simulate numerous flow scenarios intuitively while you design. SOLIDWORKS Flow Simulation is an intuitive Computational Fluid Dynamics (CFD) solution embedded within SOLIDWORKS 3D CAD that enables you to quickly and easily simulate liquid and gas flow through and around your designs to calculate product performance and capabilities. One of the most common questions I hear from users new to CFD is how do I get started? In this SOLIDWORKS Flow Simulation tutorial, I am laying out how to prepare a model for a fluid flow problem. Computational Fluid Dynamics (CFD) has been around for the past 30 years, and it has become even more user-friendly and powerful than it was 30 years ago. With the advent of technology, you can now run fluid flow problems virtually. Testing fluid flow problems used to be a fairly complicated and difficult process to execute.
