ACUSIM Software Inc.
Company Overview:
ACUSIM Software was founded to provide engineers and scientists with superior CFD (Computational Fluid Dynamics) solutions. ACUSIM has developed a robust, fast, and accurate general purpose, finite element flow solver that can be seamlessly used by all levels of expertise, both as a standalone solver and as an embedded component integrated into engineering and scientific applications.
Headquartered in Mountain View, California, ACUSIM Software markets its flagship product, Acusolve™, and associated pre-processor, AcuConsole™, through direct sales, OEM partners, and distributor channels. ACUSIM Software has customers in India, Japan, North America, South America, and Europe.
Solutions for Abaqus:
AcuSolve™ is a general-purpose finite element based flow solver, which has evolved through years of development experience and real world applications feedback. AcuSolve is a unique and significant offering in the CFD solutions marketplace. AcuSolve's advantage is its superior robustness, speed and accuracy. Users are able to rapidly obtain quality solutions without having to iterate on solution procedures or worry about mesh topologies or element types. AcuSolve™ runs on WINDOWS (32/64 bit), LINUX (32 bit/64 bit) and many flavors of UNIX, and exhibits excellent parallel scalability. AcuSolve's P-FSI capability (P stands for practical) is a fluid structure interaction capability used to predict the simulation of linear solid/structural response. When used in conjunction with Abaqus, AcuSolve picks up the model information, frequency, and mode shapes from an Abaqus ODB file, and then solves for the deformation of the structure under fluid forces/loads. The structural deformation and mesh motion is accomplished in AcuSolve™.
Additional Information:
An example of an AcuSolve P-FSI solution with Abaqus structural solution input is shown in Figure 1, a small, real-time animation. The model is from Reference 1. The fluid velocity is 51.3 m/s with flow proceeding from left to right.
A full-size version with time display and velocity scale, played back 5x slower, is shown in Figure 2 (8 MB download):
