Flow 3D is a commercial computational fluid dynamics (CFD) software used to simulate various fluid flow and heat transfer phenomena. One of its applications is in hydraulic fracturing, a process used to extract oil and gas from shale formations by injecting high-pressure fluids to create fractures. Accurate simulation of hydro crack propagation is crucial in hydraulic fracturing, as it helps engineers optimize fracture treatment designs, predict well performance, and minimize environmental risks.
FLOW-3D uses a pressure solver that does not inherently support negative pressures (tension) in the standard fluid configuration. When the fluid accelerates around a sharp convex corner (e.g., a spillway bucket or a flip lip), the Navier-Stokes equations call for a pressure below vapor pressure. The solver then sets pressure to zero, leading to a sudden void—the crack. flow 3d hydro crack fixed
If the cell size is larger than the thickness of a thin hydraulic wall, the FAVOR™ algorithm cannot resolve the solid geometry properly, creating a perceived "crack." Flow 3D is a commercial computational fluid dynamics
