OpenFOAM vs. SimFlow vs. Simpack vs. V Programming Language Comparison Chart

OpenFOAM is the free, open-source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organizations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics. OpenFOAM is professionally released every six months to include customer-sponsored developments and contributions from the community. It is independently tested by ESI-OpenCFD's application specialists, development partners and selected customers, and supported by ESI's worldwide infrastructure, values and commitment. Quality assurance is based on rigorous testing. The process of code evaluation, verification and validation includes several hundred daily unit tests, a medium-sized test battery run on a weekly basis, and a large industry-based test battery-run.

Simpack is a general multibody system simulation (MBS) software enabling analysts and engineers to simulate the non-linear motion of any mechanical or mechatronic system. It enables engineers to generate and solve virtual 3D models in order to predict and visualize dynamic motion, coupling forces and stresses. Simpack is used primarily within the automotive, engine, HIL/SIL/MIL, power transmission, railway, and wind energy industrial sectors, but can be applied to any branch of mechanical engineering. Simpack simulation software is particularly well-suited to high frequency transient analyses, even into the acoustic range. Simpack was primarily developed to handle complex non-linear models with flexible bodies and harsh shock contact.
