Hi everyone,
I am doing a simulation in which flow properties are changing with time. Is there any way to give the flow properties as a function of time.

Meaning
Hello,
What do you mean by flow properties?
We will need more information.
I know that many things can be time dependent in liggghts, but I need more specifics in order to lead you down the correct path.

Flow properties
Flow properties
1. coefficient of friction
2. coefficient of rolling friction
3. cohesion energy density

unfix and refix
Hello,
From my understanding on how the fix property/global commands are done, you should be able to do something like the following.
# Set init properties
fix m1 all property/global youngsModulus peratomtype 5.e6
fix m2 all property/global poissonsRatio peratomtype 0.45
fix m3 all property/global coefficientRestitution peratomtypepair 1 0.3
fix m4 all property/global coefficientFriction peratomtypepair 1 0.5
# Do stuff
.
.
.
# Set new properties
unfix m1
unfix m2
unfix m3
unfix m4
fix m1 all property/global youngsModulus peratomtype 6.e6
fix m2 all property/global poissonsRatio peratomtype 0.5
fix m3 all property/global coefficientRestitution peratomtypepair 1 0.25
fix m4 all property/global coefficientFriction peratomtypepair 1 0.6
You could set these new properties in a loop using labels.
