FLOW-3D 2022 r1

What’s New – FLOW-3D 2022R1

The new 2022R1 versioning of FLOW-3D products reflects Flow Science’s adoption of a synchronized release naming convention for FLOW-3D, FLOW-3D CAST and FLOW-3D HYDRO. 2022R1 represents the transition to a unified code base for FLOW-3D products. This important evolution will allow users access to the latest developments as soon as they are ready, at a more frequent product release pace.

The 2022R1 release features an extension to the FAVOR™ method called the detailed cutcell representation, the introduction of simulation templates with themed solver defaults, moving droplet/bubble sources, a new axial pump model, extensions to Active Simulation Control capabilities, tabular properties that allow users to specify complex property dependencies based on two independent variables, and additional numerics features such as a VOF-to-particle development to improve mass conservation for fluid regions subject to breakup. Streamlined GUI improvements include redesigned physics dialogs, a new initial conditions widget, and redesigned output and geometry widgets for easier, faster and error-free simulation setup.

Detailed Cutcell Representation – An Extension to FAVOR

The FAVOR™ method represents solid geometry using area and volume fractions on a regular, Cartesian grid. It enables FLOW-3D to efficiently simulate flow through and around complex geometry without resorting to unstructured body-fitted meshes. For all its considerable computational benefits, one challenge for the FAVOR™ method is that the calculation of wall shear stresses along solid surfaces can sometimes be noisy. An extension to FAVOR™, called detailed cutcell representation, greatly improves the calculation of wall shear stresses, resulting in significant improvements in the solution near solid surfaces.
