Flow Science releases FLOW-3D Version 10.0
This image shows the Von Mises stress (dynes/cm2) of a V6 engine block composed of aluminum 380 after cooling initially within a steel die for 50 sec., and then in air for 540 sec. Residual stresses develop due to uneven solidification and cooling.

FLOW SCIENCE INC. is making available the new release of its FLOW-3D computational fluid dynamics software. FLOW-3D version 10.0 features fluid structure interaction and thermal stress evolution models that simulate and analyze the deformations of solid components and solidified fluid regions and resulting stresses in response to pressure forces and thermal gradients. The models use a combination of conforming finite-element and structured finite-difference meshes.

Current users will experience a boost in speed with the implementation of SMP parallelization across the board for almost all models in FLOW-3D v10.0, the developer explained.

Among the program’s important models and improvements, Flow Science lists:
• Fluid structure interaction model;
• Thermal stress evolution model;
• Iron solidification model;
• Granular flow model;
• Surface wave generator additions;
• Moisture drying model;
• Solid solute dissolution model;
• Extended SMP parallelization; and,
• An optional materials properties database.

“Version 10 is one of the most important releases in the history of FLOW-3D,” stated Michael Barkhudarov, Flow Science Inc. v.p. of Research and Development. “The code has advanced tremendously with the addition of the fluid structure interaction and thermal stress models, both of which give our users even more sophisticated and fundamental numerical modeling capabilities.”

Customers currently using FLOW-3D will be provided with the new version under their maintenance contracts.
