1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Flow Simulation Meshing: Part 1Basic and initial mesh, global refinement level and minimum gap size.↗ Flow Simulation Meshing: Part 2Manual basic mesh settings, control planes and local mesh controls.↗
2. Key takeaways
The basic mesh divides the computational domain; the initial mesh refines it according to the geometry before the calculation.
In automatic mode, the global refinement level and the Minimum Gap Size drive most of the result.
In manual mode, control planes and local meshes concentrate cells where the flow matters.
Always display the mesh on a cut plot before running a long calculation.
Tip
Check the Minimum Gap Size whenever you change the project settings: in a narrow passage, it often decides whether the passage is meshed correctly.
