I am now using the CFDEM for modelling the soil erosion.
As far as I know, the void fraction of the CFD cell, which is the particle volume in each CFD cell, is calculated with the particle information like particle size and location. I'd like to edit the void fraction manually with consistent ratio.
If the values of actual void fraction are 0.1, 0.2, and 0.3, then I like them to be 0.2, 0.4, 0.6.
Is is possible to adjust the void fraction value manually with consistent ratio?
Thanks in advance,
