Altair AcuSolve™

General Purpose Fluids and Thermal Simulation

For an analyst performing advanced computational fluid dynamics (CFD) modeling or a design engineer quickly needing to understand fluid or thermal effects on a design proposal, Altair offers a complete set of tools to support each project. From detailed component analysis to full systems performance, Altair provides a range of scalable solvers and robust pre- and post-processing software for CFD.

AcuSolve® is a proven asset for companies looking to explore designs by applying a full range of flow, heat transfer, turbulence, and non-Newtonian material analysis capabilities without the difficulties associated with traditional CFD applications. AcuSolve is robust, scalable, and accurate regardless of the quality and topology of the mesh elements. No CFD software gets you to your end goal sooner: analyzing results and exploring the physics of products.

Why AcuSolve?

Focus on Solving Real Design Problems

Provides a robust process to obtain accurate fluid and thermal results with only minimum interaction from the user.

Greater Multi-disciplinary Collaboration

Naturally suited for interaction and co-simulation with finite element-based structural solvers, stemming from a common analytical base.

Fast and Accurate CFD Analysis

Scientifically-proven numerical methods deliver rapid linear and nonlinear convergence rates for both steady state and transient simulations.

Key Features

Implicit Solver

With AcuSolve’s implicit time stepping, take larger time steps while maintaining accuracy.

No Graphic

Second-order Accurate in Space and Time

AcuSolve is second-order accurate in space and time, without needing to initiate the model with first-order simulation. 

No Graphic

Coupled Velocity and Pressure

Quickly solves coupled velocity and pressure systems while maintaining stability.

No Graphic

Steady State Time Marching

Steady state convergence is reached quickly, for many problems in fewer than 100 iterations, increasing simulation throughput. 

No Graphic

Stable Long Transient Analysis

Simulate thermal events to their completion with confidence:  AcuSolve’s stability during long transient analyses is unparalleled. 

No Graphic

Insensitivity to Mesh Quality

While in some other CFD codes mesh quality affects accuracy and reliability, AcuSolve does not require a perfect mesh.

No Graphic

Minimum CFL Constraints

Not constrained by traditional Courant-Friedrichs-Lewy (CFL) parameter limitations. 

No Graphic

Massively Scalable

From its inception, AcuSolve‘s architecture leverages massively parallel machines and scales reliably for every simulation need. 

No Graphic

GPU Accelerated

AcuSolve’s speed is further enhanced by exploiting locally-available resources through GPU acceleration.
