Ansys

Engineers set up a model, apply loads and boundary conditions, and solve to see stress, airflow, heat, or electromagnetic behavior. Machine learning features help speed up some studies. It is common in aerospace, automotive, energy, and electronics.

Licenses are expensive and aimed at companies and universities, and learning the products takes time. Synopsys acquired Ansys, so product branding may change.

Altair, COMSOL, and Siemens Simcenter are alternatives. Ansys suits engineers who need validated simulation for certification or design work.
