There are two basic types of systems: analysis systems and component systems. The Fluid Flow (Polyflow) analysis system allows you to perform a complete CFD analysis and contains cells that allow you to: create geometry, generate a mesh, specify settings in Polydata, run the Polyflow solver, postprocess solution data plots in Polycurve or statistical information in Polystat, and visualize the results in Ansys CFD-Post.

The Polyflow component system allows you to access the Polyflow application from within Workbench, and contains only the cells needed to specify settings in Polydata, run the Polyflow solver, and postprocess solution data plots in Polycurve or statistical information in Polystat. When using a Polyflow component system, a mesh must be imported into the system or provided through a connection from an upstream system. You must also connect the Polyflow component system to a Results component system if you want to postprocess the results using Ansys CFD-Post.
