DES Grid Partitions in SQP

MFiX How to
#1

Hi Dr. @jeff.dietiker, @cgw, in my SQP setup, currently, “Search grid partitions” are 10, 50, 10 and it says “optional”. What would happen if I do not enter any of these three entries?

From tool-tip, I think, these are automatically adjusted to three times of particle-diameter? At the moment, if I give cell width less than 5 times of particle-diameter, GUI shows up an error.

Reducing cell-width to three times of particle-diameter is beneficial in my setup. Please let me know.

Thank you,

Hi Team, just wanted to follow up on this, if you have any feedback / suggestions. Is it okay to leave them blank? Thank you,

If you leave them blank, it will be automatically computed at run time such that the des grid spacing is 3 times the max diameter. It should be OK to leave blank, but you can experiment to see if different values provide better performance.

Thank you, Dr. @jeff.dietiker. I’d try leaving them blank and run setups.
