AcuSolve's proprietary numerical methods produce stable simulations and accurate results, regardless of the quality and topology of mesh elements. When combined with unstructured and automated mesh, no CFD software takes you to your ultimate goal sooner: analyzing results and exploring the physics of your application.
AcuSolve's unique solver architecture and evolving feature set provide a valuable tool for any company tasked with performing CFD analytics.
Benefits
Robustness
AcuSolve's powerful troubleshooting technology provides users with the most robust solution in the CFD market. AcuSolve's proprietary numerical methods produce stable simulations and accurate results, regardless of the quality and topology of mesh elements. Preprocessing and mesh ing have historically been the bottleneck in the execution of industrial CFDs. However, AcuSolve's troubleshooting technology, combined with automated unstructured meshes, reduces preprocessing load and enables scientists and engineers to achieve their ultimate goal more quickly by analyzing results and exploring the physics of your application. AcuSolve achieves all of this without requiring users to run numerous executions to explore different solution procedures. AcuSolve uses a single solver for all flow regimes with very few parameters to adjust. No adjustment required.
Rapidity
AcuSolve produces results quickly, solving the fully coupled pressure/velocity equation system using industry-leading and scientifically proven numerical techniques. This generates fast linear and nonlinear convergence rates for steady state and transient simulations. In addition to the efficiency of numerical methods, AcuSolve has been architected from the ground up to make the most of parallel computing platforms. All solver algorithms are designed for parallel clusters of multiple cores, using a hybrid parallel model of distributed/shared memory (MPI/OpenMP) that is completely automated within the solver execution script.
Message Passing Interface (MPI) is used for communication between distributed memory machines, and shared memory data copying is used between subdomains of a single shared memory machine. Two-level domain decomposition is used to optimize the distribution of elements and nodes based on the passing requirements of shared and distributed memory messages in a given simulation. These optimizations ensure that message transmission overhead is kept to a minimum.
Precision
AcuSolve's numerical methods have been customized to provide speed and accuracy for the most demanding CFD applications. One of the keys to its accuracy is the use of equal-order interpolation for all variables. This results in second-order spatial precision for all equations that govern. This focus on accuracy further enhances solver speed, allowing you to achieve high levels of accuracy with AcuSolve using much less mesh than necessary to achieve comparable results using other cfd solvers on the market. In addition to requiring less mesh to produce a comparable result, AcuSolve is able to maintain its second-order accuracy in all element topologies. You can confidently simplify your preprocessing by using tetrahedral elements to merge your domain without sacrificing robustness or accuracy.
In addition to exceptional spatial accuracy, AcuSolve provides second-order accuracy in time as well. This provides unparalleled transient simulation capabilities. Running a transient in AcuSolve is easy, as well as specifying that the simulation is transient, selecting an appropriate time step to resolve the physics, and starting the solver. It's that simple. No complex solver configuration to be adjusted, no CFL-based stability limits, and no concern for divergent simulation due to incorrect solver selection!
