We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Slightly difficult to explain as there are a few factors to consider. 

  • Post processing surfaces interpolate data from the adjacent cells. A pre-meshed surface (boundary condition surface) uses the data that's actually stored on that surface. 
  • Lines have no area, so field values are usually fairly smooth, area values may be a little less smooth.Â
