To get the "extra quality" performance you desire, your hardware must be up to the task. CFD is computationally intensive.
SolidWorks Flow Simulation is an integrated computational fluid dynamics (CFD) add-in for SolidWorks CAD that simulates fluid flow, heat transfer, and related physics inside and around CAD models. "Extra Quality" typically refers to solver/mesh settings that increase solution accuracy by refining the mesh, tightening convergence criteria, and increasing solver iterations — at the cost of longer run times and higher memory use. download solidworks flow simulation extra quality
