Physics Simulation
COMSOL is the gold standard for accurate simulation of physics effects and one of the strongest competitors to Ansys. Where the software shines is in solving multiphysics problems that depend on several phenomena—you can simulate everything, including black holes. The modular aspect of COMSOL helps professionals customize the software to their desires, which can be run with a single module or a whole multitude of collaborating modules for more demanding tasks, as well as with two-way communication with external programs, such as CAD software.
Chemistry Simulation
NAMD is developed by the University of Illinois and helps researchers simulate the dynamic interactions between molecules and atoms. It is an established means of molecular dynamics simulation that scales from individual clusters of molecules to full-on chemical interaction in different phases. Parallel simulation modes help differentiate NAMD from its peers, allowing efficient problem solving of larger systems using the Charm++ parallel programming model as the base.
