'FFCP Left Extruder Cooling Duct' simulation project by DrLex


I created a new simulation project called 'FFCP Left Extruder Cooling Duct':

Optimize the airflows in a custom cooling duct for the Flashforge Creator Pro and similar 3D printers. The current model is at https://www.thingiverse.com/thing:2436915

This is a bit of special case because I want to simulate both the internal flow, as the external flows exiting the exhausts. Therefore I pretend the outside region I’m interested in, is still part of the internal volume. We’ll see how well this works…

More of my public projects can be found here.


Woohoo, I have my first result after working around some problems. Splitting this STL into surfaces is finicky for some reason. I slightly simplified the mesh and tried some different split angles until it finally worked.

The result confirms what I observed from testing this duct: there is a dead zone behind the nozzle. Moreover, the left exhaust gets too much flow compared to the right. Now it's tweaking time.


Good job @DrLex!
