General-Purpose Navier-Stokes (NS) Solver
Altair Acusolve
Description
Acusolve is a general-purpose Navier-Stokes (NS) Solver, an 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. Robust, scalable, and accurate regardless of the quality and topology of the mesh elements.
Key Features
Implicit Solver
Implicit time stepping enables users to take larger time steps while maintaining accuracy.
Second-order Accurate in Space and Time
The solver is second-order accurate in space and time, without needing to initiate the model with first-order simulation.
Coupled Velocity and Pressure
Quickly solves coupled velocity and pressure systems while maintaining stability.
Steady State Time Marching
Steady state convergence is reached quickly, for many problems in fewer than 100 iterations, increasing simulation throughput.
Stable Long Transient Analysis
Simulate thermal events to their completion with confidence: unparalleled stability during long transient analyses.
Insensitivity to Mesh Quality
No perfect mesh is required unlike other CFD codes where mesh quality affects accuracy and reliability.
Minimum CFL Constraints
Not constrained by traditional Courant-Friedrichs-Lewy (CFL) parameter limitations.
Massively Scalable
The architecture leverages massively parallel machines and scales reliably for every simulation need.
GPU Accelerated
Speed is further enhanced by exploiting locally available resources through GPU acceleration.
