Altair HW Acusolve 14.0.301 Hotfix
Advanced Technology,
Accurate Results
AcuSolve is based on the Galerkin/Least-
Squares (GLS) finite element method.
GLS is a higher-order accurate, yet stable
formulation that uses equal order nodal
interpolation for all variables, including
pressure. The method is specifically
designed to maintain local and global
conservation of relevant quantities under
all operating conditions and for all meshes.
In addition to excellent spatial accuracy,
AcuSolve has a second-order time
integration option. Since AcuSolve obtains
rapid nonlinear convergence within each
time step, temporal accuracy is achieved
in practice.
AcuSolve has a very rich mathematical
foundation, translating into superb numerical
behavior. AcuSolve can easily solve the
largest and most complex mission critical
industrial problems.
Robust Solution
AcuSolve typically solves a given problem in
the first attempt. Fully converged solutions
are reliably obtained using AcuSolve’s
efficient steady-state solver. Nonlinear
convergence remains strong even as
solutions approach their final result.
Two key components contribute to this
robustness: the GLS finite element
formulation, and a novel iterative linear
equation solver for the fully coupled
pressure/velocity equation system.
This powerful iterative solver is highly
stable and is capable of efficiently handling
unstructured meshes with high aspect
ratios and badly distorted elements
commonly produced by fully automatic
mesh generators. This linear solver yields
significant stability and convergence
advantages over the segregated solution
procedures commonly found in many
commercial incompressible flow solvers.
High Speed,
Parallel Performance
AcuSolve achieves fast solutions via
three mechanisms:
•
Solution of the fully-coupled pressure/
velocity equation system, which
yields significant linear and nonlinear
convergence speed.
•
Architected from the ground up for vector
and cache-based super-scalar computers.
•
All algorithms are designed for multi-
core parallel clusters, using a hybrid
distributed/shared-memory (MPI/OpenMP)
parallel model. The parallelization is
completely transparent to end users.
