    Vivid Numerics can analyze transient and steady state behaviour of mechanical systems. A steady state analysis of the contact between gear teeth was completed here. The contact between the teeth was modelled using non-linear frictional contacts.

    A thermal FEA analysis was conducted to determine the energy loss from a building. Because the forced convective heat transfer coefficient was not known the FEA analysis was coupled with a CFD analysis. The CFD analysis calculated the heat transfer from the outside of the building walls to the environment while the FEA analysis calculated the heat transfer through the walls, windows and doors. This is a straightforward FSI analysis that gives accurate energy loss results from a structure.
    Vivid Numerics is experienced in code-based analyses. Shown alongside is a hot-tapped branch connection which was reinforced to comply with the provisions of CSA Z662. Stresses were linearized using the stresses generated from the internal pressure combined with the loading from thermal expansion strains. The linearized stresses were then compared to the allowable stresses in ASME Boiler & Pressure Vessel Code Section VIII Division 2.

    Vivid Numerics utilized FSI (ANSYS CFX coupled with ANSYS mechanical) to determine the gas pulsation levels and resulting pipe stresses in a 3 stage compressor skid. This information was used to develop the piping support structure. The piping stress and displacements had to pass API 618 criterion. Valve actuator masses and geometry as well as porous domain location and properties were all taken into account in the analysis. Videos can be seen of this analysis here.
    Multicomponent flow was analyzed using CFX to determine the mixing performance of an inspirator. The goal was to achieve a good methane to air ratio for a combustion process. In the figure on the right, the left figure shows the methane to air ratio for the original design. After implementing Vivid Numerics recommended changes the methane to air mixture was much more even as shown on the right. This was backed up by experimental testing with prototypes machined and printed through Area 51 Machine Design.
