ASCII export for a 1 way coupled sim
Hello,
I want to import velocity field from fluent as an ASCII file. I read the help document here https://2022.help.altair.com/2022.2/EDEM/Creator/Physics/Field_Data_Manager/new_topic.htm
[3D Vector: X Y Z dx dy dz]
I am confused as to what X, Y, Z and dx, dy, dz mean
For my case since I need to import velocity does X, Y, Z mean the x, y and z component of velocity?
(fig 1)
and does dx, dy and dz mean the coordinate axes for each velocity vector?
(fig 2)
Thanks,
Kiran
Hello Stephen,
Thanks for your reply.
Please correct if I'm wrong, does dx, dy & dz mean velocity in x, y and z?
Thanks,
Kiran

Hi Kiran,
That's correct, the x,y,z components of the velocity vector.

Can I use EDEM to study nanoparticles dispersed in a fluid domain? Are there any solver restrictions when it comes to particle size in general or with respect to a 1 way coupled simulation?

Hi Kiran,
You may begin to see some non-physical behaviour below 1 micron in size, so I would not recommend nano-particles directly however you can always test to confirm for your case.
You can also consider some form of dimensionless scaling if you are looking to model this, however also worth considering the overall number of particles you would have to simulate.

Hi Kiran,
X,Y and Z are the positions of the field in SI units (meters). dx,dy,dz are the field (velocity) values.
