Kaczmarek:We import STL files. The traditional drawback to an automated system is that it has to work with watertight geometry, and defeaturing results in an inaccurate model representation. We overcame this challenge by implementing surface healing algorithms from Polygonica, which work stunningly fast...
Process performance is optimized by introducing internal structures to guide the flow. Despite a significant increase in the mass transfer coefficient (kLa) through internal modifications, the CR-IL-ALR still exhibited the poorest performance. The optimized AR-IL-ALR demonstrated good mixing and, ...
