About Us

CertaSIM, LLC was founded in 2011 as the distributor of the IMPETUS Afea Solver® for North, Central and South America. Our core expertise is in simulation of nonlinear dynamics problems. We do not compete with our customers so our goal is to provide the best technical support and training to make their job easier. Our technical staff has many years of experience with transient dynamic analysis and support of commercial software.

We believe that the IMPETUS Afea Solver® is the most accurate and robust explicit dynamic solver on the market today. It is the only commercially available explicit dynamic finite element solver that takes full advantage of GPU Technology for massively parallel processing on a single workstation or a single node of a cluster. This allows our customers to run the most demanding problems on a standard workstation configured with the latest hardware.



"After an evaluation phase of IMPETUS software - we were in business"

Manager R&D, Medium & Large Caliber Division, Nammo.


"The IMPETUS Afea Solver with the SPH Module are ideal for Fluid-Structure Interaction simulations with large deformations and moving boundaries typical in biomedical engineering."

Milan Toma, Ph.D.
Assistant Professor, BioFSI Lab at New York Institute of Technology.

"IMPETUS is an extremely accurate explicit dynamic solver. We support HEX64 elements specifically for IMPETUS. Now, engineers can create meshes that can be solved with IMPETUS on a GPU in a fraction of the time it takes other solvers."

Paul Ressler
Director of Sales and Marketing, csimsoft.

"When I first started in the FEA industry 14 years ago we had 2 core desktops and any analysis with more than 100,000 elements took days to run. With IMPETUS and its GPU processing I now have thousands of cores in my desktop and the same analysis takes minutes of computational time"

"Biomedical fluid-structure interaction problems require robust, high-order elements capable of large deformations, as well as a robust framework for fluid-solid coupling, and are among the most challenging class of finite element simulations. Impetus has become our go-to framework. Impetus makes this class of problems easy with the most robust high-order elements available commercially and seamless fluid-solid coupling with SPH particles. Typically requiring expensive supercomputers, Impetus is the only software out there that reliably delivers this capability in on an inexpensive GPU machine."

"I have been using several finite element packages for close to twenty years to simulate various engineering problems with impact and shock. While all of them can model problems with a reasonable level of accuracy, they are typically slow with need to adjust many parameters. I was therefore pleasantly surprised when I was used non-linear Explicit Finite Element code IMPETUS Afea Solver. The improvement of simulation speed is phenomenal. This speed when combined with improvement in accuracy, makes IMPETUS, a software to consider seriously by any researcher working in this area."
