Blue Ridge Numerics’ latest CFdesign CFD software (v9) is said to enable users to set up and view first-pass CFD simulations in minutes while generating high-fidelity design reviews up to 20 times faster than previous versions. It also includes new analysis features.
‘Auto mesh sizing’ performs a comprehensive topological interrogation of the geometric model, assigning mesh sizes based on curvature, geometric gradients and proximity to neighbouring features. An optimally sized surface and volume mesh ensures faster mesh generation and higher-quality simulation results without any user input.
The new ‘rules on parts’ feature intelligently detects MCAD part names within an assembly and automatically assigns volumetric boundary conditions and material properties. Boundary conditions include heat generation and total heat generation, both of which can be steady-state, transient or temperature dependent. Materials are assigned from a customisable library of fluids, solids, printed circuit boards and the newly added two-resistor electronic components.
The new Accelerant Solver within v9 uses proprietary CPU optimisation algorithms to radically reduce the time it takes to achieve fully converged fluid-flow and heat-transfer results.
