The Simcenter FLOEFD automatic fluid volume detection and automated meshing techniques are designed to work directly with CAD geometry. It can handle complex or variable quality geometry without the need to simplify models. SmartCells Technology is at the core of efficient automatic meshing with the Simcenter FLOEFD robust cartesian immersed boundary grid method. SmartCells can resolve many solid and fluid regions accurately within a single cell, subdividing it into multiple control volumes for calculation. This is crucial to meshing complex CAD models, including automatically dealing with challenging conditions like interfering geometry or very thin volumes. Simcenter FLOEFD applies automatic mesh refinement based on geometry features, and solution adaptive refinement can be enabled for efficient mesh resolution of regions with higher flow and thermal gradients. There are options available for local meshing and manual controls for engineers desiring more precise control of the mesh.
Simcenter FLOEFD meshing and solver technology provides a unique combination of classic 3D finite-volume numerical approaches with empirical and analytical methods to simulate CFD problems. A comparatively coarse mesh can be generated quickly and easily, which is very efficient and stable to solve compared to typical CFD software, while still maintaining relatively high accuracy.
A step change of going from days to hours, or hours to minutes for meshing is often reported when Simcenter FLOEFD is adopted. The innovative meshing technology of our CAD-embedded approach allows design engineers and non-specialists to reliably conduct CFD analyses early in the design process. It also provides a fast and efficient alternative approach for experienced analysts to tackle a wide range of typical CFD problems.
