why lift force treatForceExplicit set as true

Hi all,

As far as I know, explicit consideration of forces is not available in CFDEM cause only implicit momentum exchange is implemented. But why in the MeiLift.C Line 82 "forceSubM(0).setSwitches(0,true); // enable treatExplicit, otherwise this force would be implicit in slip vel! - IMPORTANT!" appears. One should set the treatExplicit as false anyway, right? The same situation happens to the virtualMassForce as well.

Cheers,
Linhan
