SOLIDWORKS FloXpress is a first-pass basic fluid flow analysis tool that calculates how water or air flows through part or assembly models. Based on the calculated flow trajectories, you can find problem areas in your design and improve them before you manufacture your parts. SOLIDWORKS FloXpress comes with every SOLIDWORKS 3D CAD software package.
When you are ready to do a full CFD analysis, it is easy to upgrade to SOLIDWORKS Flow Simulation.
