An OpenFOAM job typically involves using the OpenFOAM software suite for computational fluid dynamics (CFD) simulations. Professionals in this role set up, run, and analyze fluid flow simulations for applications in engineering, physics, and other scientific domains. Responsibilities may include developing custom solvers, optimizing simulation performance, and integrating OpenFOAM with other tools. Such jobs are common in industries like aerospace, automotive, energy, and research institutions. Proficiency in Linux, C++, and numerical methods is often required.
