FLOW-3D’s efficient workflow provides engineers more time to do what you do best—analyzing, designing and optimizing better designs.
FLOW-3D uses an innovative numerical scheme to track the location of surfaces and apply proper dynamic boundary conditions at those surfaces. The accuracies have proven themselves over the past three decades and the computational efficiency is unmatched.
FLOW-3D’s approach to gridding combines the advantages of simple rectangular grids with the flexibility of deformed, body-fitted grids. Fixed grids of rectangular control elements are simple to generate, possessing improved accuracy, smaller memory demands, and simpler numerics. Grids or geometry can be changed independently, eliminating labor intensive methods required for body-fitted or finite-element grids. Linked, nested and partially-overlapping mesh blocks provide effective enmeshing of complex, multi-scale domains and concentrate resolution in areas of interest.

FLOW-3D offers simple, efficient and robust meshing capabilities—allowing for local refinement in areas of interest, and maximizing computational resources. Small obstacles, complex geometries and thin channels can be accurately resolved using one of the several multi-block meshing capabilities. Linked mesh blocks can be used only to mesh the areas of interest and limit the total number of computational cells. Nested mesh blocks can be used to enhance the resolution around an area of interest. Conforming and partially overlapping mesh blocks can be used to resolve irregularly shaped fine features with sharp changes in scale that otherwise cannot be simply resolved using nested mesh blocks. FLOW-3D also allows body-fitted finite element meshes to model Fluid-Structure Interaction. These body-fitted meshes can be automatically generated with FLOW-3D or simply imported from external CAD packages. All these meshing techniques gives users the flexibility to create meshes that are simple, and efficient, reducing simulation turnaround time and improving solver performance.
