New run
Five steps: pick a geometry, choose the physics and say what happens at each boundary, confirm the solver settings, choose where it runs, launch.
This is CAD, so it has to be meshed. How it should be meshed depends on the physics — a wind tunnel around the part is one thing, the part itself is another — so that comes next, once you have said what you are simulating.
Need sweeps, solver plug-ins, raw configuration or a mesh study? New job exposes everything.
