XFlow FLUIDS SIMULATIONS TO IMPROVE REAL-WORLD PERFORMANCE

XFlow OVERVIEW In the modern competitive world of product innovation, industries demand the complex simulation of their product’s real-world behavior under extreme conditions; such as vehicles wading, powertrain lubrication and critical flight maneuvers, XFlow offers particle-based Lattice-Boltzmann technology for high fidelity Computational Fluid Dynamics (CFD) applications as a part of SIMULIA’s Fluids Simulation portfolio. The stateof-the-art technology of XFlow enables users to address complex CFD workflows involving high frequency transient simulations with real moving geometries, complex...

SOFTWARE ENVIRONMENT Unified Pre-processor, Solver and Post-processor XFlow provides a unique and novel interface and working environment for the user. The pre-processor, solver and post-processor are fully integrated in the same environment. The User Interface layout is fully configurable with movable workspace windows and options to use pre-set display settings. Pre-processing Being particle-based, the algorithms behind XFlow lower the requirements imposed on the CAD models. For example, in the analysis of powertrain lubrication, the software is not concerned with moving or crossing surfaces...

Adaptive Wake Refinement XFlow automatically adapts the resolved scales to the user requirements, refining the quality of the solution near the walls, dynamically adapting to the presence of strong gradients and refining the wake as the flow develops. Single Consistent Wall Model XFlow uses a non-equilibrium wall function to model the boundary layer. This wall model takes into account the adverse pressure gradients responsible for flow separation, important in aerodynamics analysis. Moreover, the wall model is automatically disabled as soon as the lattice size near walls is small enough to resolve...
