General-purpose NS Solver (Altair® AcuSolve®) 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.
