FLOW-3D and its family of products are used around the world in both R&D and production settings, to tackle the most challenging CFD problems where free-surface modeling is prevalent. In metal casting, tracking the metal front during filling is important in predicting casting defects and the strength and precision of the cast part. In civil and environmental engineering, it is crucial to accurately track the water interface. In aerospace, engineers account for the sloshing of fuel in aircraft and spacecraft tanks. In additive manufacturing, FLOW-3D models sophisticated AM processes such as powder bed fusion at a detailed level. FLOW-3D is used for laser welding where the dynamics of the melt pool plays a critical role in the consistency and strength of the weld seam. In the automotive industry, FLOW-3D is used for the toughest CFD problems in transmission and gear modeling as well as cooling and fuel systems. FLOW-3D is popular in modeling consumer products such as filling shampoo and detergent bottles. In biomedical applications, whenever a free-surface is present in the problem, FLOW-3D excels in simulating those systems. And FLOW-3D is routinely used for coating applications.
