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.

Just a note on scale. Do NOT build the channel in real scale: CAD kernel tolerances tend to merge micron scale parts into a corrupted mess. Scale up and then rescale in Fluent when you import the mesh. A 2mm channel should be fine, 20microns will almost certainly not be.Â
