Use Case: A pump manufacturer testing a new impeller geometry. Premium simulation reveals cavitation clouds forming at the tip of the blades during high-RPM operation. By tweaking the blade angle virtually, the engineer eliminates the cavitation before cutting a single metal prototype, saving thousands in tooling costs. Perhaps the most powerful feature in the Premium suite is FSI. This allows the software to solve for fluid flow and structural stress simultaneously. While many tools offer "one-way" FSI (fluid pressure mapped to a solid), Premium supports two-way FSI for transient analysis.
Flow Simulation Premium includes models for shear-thinning (pseudoplastic) and shear-thickening (dilatant) fluids, as well as viscoplastic materials that require a yield stress before they begin to move (like ketchup or toothpaste). solidworks flow simulation premium
Use Case: Designing a micro-pump for lab-on-a-chip devices. The flexible membrane deforms under hydraulic pressure. Standard simulation would assume a rigid wall, leading to inaccurate flow rates. Premium FSI captures the flutter and deflection, allowing precise prediction of pumping volume per cycle. One of the most underrated benefits of the Premium version is the "What If" study management . Because the solver is fully embedded in SolidWorks, engineers can use CAD parameters (like hole diameter or fin height) as design variables. The software can then run a "Design of Experiments" (DOE) automatically, ranking which geometric feature has the greatest impact on pressure drop or heat transfer. Limitations and Hardware Considerations No tool is perfect. SolidWorks Flow Simulation Premium operates on a Cartesian mesh with immersed boundary technology. While this is incredibly fast (no time-consuming body-fitted meshing), it struggles with extremely thin gaps or highly anisotropic geometries (like long, thin pipes versus large vessels).
