Flow3DMP helps design engineers to take advantage of the power of highperformance compute clusters to tackle problems with very large domains or long run times The physical models and numerical methods of Flow3DMP v6 are based on Flow3D v11

High-Performance Computing Version of CFD for Metacasting

Faster simulations, decreased use of memory Fully synch’ed with Flow-3D v.11, including postprocessor Shipping now to maintenance subscribers

FLOW SCIENCE INC. released a high-performance computing version of its computational fluid dynamics software, Flow-3D/MP v6, fully synch’ed with the latest developments in Flow-3D version 11, including the addition of Flow Science’s state-of-the-art postprocessor, FlowSight.

Flow-3D/MP v6.0 has the same physical models, features, and graphical user interface as Flow-3D v11.

The developer indicated it has started shipping the new release to Flow-3D/MP customers under maintenance contracts.

New features in Flow-3D v11 and available in Flow-3D/MP v6.0 include: multi-block gridding with nested, linked, partially overlapping and conforming mesh blocks; mesh quality checking; and import/export finite element meshes via Exodus-II file format.

Performance improvements — including both increased speed for simulations and a decreased use of memory — have been achieved using automatic domain decomposition, dynamic thread balancing, improved memory management, optimized MPI communication and hybrid MPI-OpenMP technology.

For especially large simulations, a decrease of 20-24% in memory usage and speed-up of 30-40% has been shown in a typical metal casting simulation from the previous version of Flow-3D/MP.

Flow-3D/MP offers multiple standard functions for metalcasting processes, including thermal stress and deformations; iron solidification; sand core blowing; sand core drying; permeable molds; solidification and melting; solidification shrinkage with interdendritic feeding; micro and macro porosity; binary alloy segregation; thermal die cycling; surface oxide defects; cavitation potential; lost-foam casting; semi-solid material; core gas generation; back pressure and vents; shot sleeves; air entrainment; temperature-dependent material properties; and cooling channels.

“Flow Science has long recognized the competitive advantage HPC-enabled tools such as Flow-3D/MP provides to our customers. Flow-3D/MP gives our users the ability to study more design alternatives in a shorter amount of time than ever before, pushing product performance to new heights,” stated v.p.-engineering John Ditter.

A new remote solving capability allows MP customers to submit their simulations to a remote cluster using client-server technology. This added functionality will allow customers to easily access all of their available hardware resources and manage their simulations in a straightforward and productive way.
