  • The Myths of CFD
    , faster, and less expensive. The disadvantages of earlier CFD programs, however, persist as myths and stand in the way of engineers using CFD in the early phases of design. These myths help explain why only about 30,000 out of over 1 million mechanical-design engineers worldwide use CFD to simulate fluid
  • Best practices for CFD simulations
    classes are the best place to learn a CFD program. But even after the classes, users need help getting the most from the simulation software. That help, in the parlance of management gurus, is called best practices. and developer of Cfdesign software in Charlottesville, Va., offers several best
  • Cool LEDs, Thanks to CFD
    the thermal-management problem. Voxdale President Ken Beyers modeled the light in Pro/Engineer. Program inputs for CFD included materials for the housing, heat sink, and PCB. The CFD analysis also included values for properties of the material connecting the LEDs to their aluminum heat sink, as well
  • CFD brings a better water turbine
    CosmosFloWorks includes a rotating frame of reference to simulate blade rotation. Results include forces generated by flow on the blades, and rotor torque. Analysis predictions closely matched experimental results. Springfield, N.J., used CosmosFloWorks CFD and FEAprogram CosmosWorks, both from "We created
  • FE Update: CFD simulations say goodbye to physical prototypes
    Chopper pumps made by our company chop the solid debris in liquid waste into smaller pieces so it can be pumped to other locations. The pump design dates from the 1960s, but it chops rope, copper wire, cloth, and even 1-in.-diameter plastic rods. Our recent adoption of CFD software lets us look
  • FE Update - Probability analysis goes beyond linear static
    and CFD programs. Linking is necessary because after each analysis, the statistical program selects another set of parameters based on one of several user-selected functions. "One way to select variables would be a mean-value-based method, " says Eric Fox, vice president of technology with the developer
  • One model, many simulations
    Software developer MSC.Software, Santa Ana, Calif., says it has developed a method that lets design teams use one model for a wide range of simulations, such as motion, CFD, and thermal, as well as to represent linear and nonlinear aspects. The jet engine is modeled in Catia but stress, CFD
  • PAT and the Crystallization Toolkit
    generated using CFD. The effect of anti-solvent addition location on the MSZW was investigated experimentally and by combining this data with a CFD model, generated using a software package by Fluent (Lebanon, N.H.), the most suitable addition location was identified as the region where velocity
