Blue Ridge Numerics has released its Upfront CFD software called CFdesign v7.0. This software includes a Solid Motion Module suitable for use by mechanical engineers during the conceptual and detailed design stages of the product development process. Available as an integrated solution for Autodesk Inventor, Pro/ENGINEER Wildfire, SolidWorks, Solid Edge, Unigraphics, and I-DEAS, CFdesign v7.0 the Solid Motion Module provides an effective virtual prototyping environment to accelerate the cost-effective production of high performance pumps, fans, blowers, compressors, turbo machinery, valves, pistons, hydraulic rams, and other products. It puts native 3D solid components and assemblies in motion, showing the interaction and effects between the physical device and its fluids environment. The simulation is parametric and associative with the MCAD model throughout the design optimization process. All design changes are made in the MCAD environment, CFdesign v7.0 automatically generates an optimal mesh to insure a quality solution, and first iteration simulation results are available for highly interactive viewing within minutes. For translating devices, CFdesign v7.0 allows user-controlled solid-body motion to occur within a flow regime. Solid objects can move in and out of the fluid domain, and the flow will respond to their movement. Application examples include pistons, hydraulic rams, and belt-driven machinery. For rotational devices, the user is given ability to analyze the flow within the blade passages. The interaction between rotating and non-rotating geometry can be dynamically and interactively explored in a manner not possible with physical testing. A classic example is the interaction between the rotor and the stator in an axial compressor or turbine. Another example is the influence of a volute on the flow from a centrifugal pump impeller.
