Easy to use, task based meshing workflows and Mosaic technology coupled with Fluent’s CFD solvers deliver great results, without compromise.

A streamlined workflow facilitates multiphase simulation setup. A single, tabbed panel organizes setup into a logical, step-by-step flow. In a benchmark gas–liquid pipe flow simulation, the new setup proved 25% faster.

An algebraic interface area density (AIAD) model accurately simulates complex multiphase regime transitions.

A detailed electrochemistry model optimizes lithium-ion battery cells.

Harmonic analysis in ANSYS CFX is 2X faster and can now solve for multiple base frequencies.

Complex fluid-structure interaction problems can be set up and solved faster and more easily.



Accurate materials information is essential for any product development organization, particularly one aiming to make pervasive use of simulation. In ANSYS 2020 R1, ANSYS GRANTA MI has an enhanced user experience, which supports the rollout of the gold standard corporate materials information management system across large engineering enterprises. With GRANTA MI, you can ensure consistency, lower risk, increase efficiency and drive innovation.
