Simulating Dry Powder Inhaler using MFiX-DEM

mixer.mfx (10.7 KB)






Dr. Waldman,
Thank you.
I started to go over the tutorial case on 3D Mixer. However, I got error message when I tried to generate mesh. I still ran it. Attached are some movie files. I am attached the .mfx file as well. In my case, however, the whole STL file (inhaler) is rotating. Do I need to change in usr1_des.f the direction of rotation etc. to start this ? Please suggest. Also, as I tried to change the particle diameter to 1 mm the particles seem to fly away.

On another note, we plan to use around 1 million particles. Is MFiX-DEM appropriate for that or I have to use GPU or MFiX-EXA ?
Please let me know.
I look forward to hearing from you.
Thanks and Best Regards,
Sincerely,
Debashis
