Hi all,

I want to find the maximum y-coordinate of the particles in my model during the simulation run. Can someone help me or give me any clues?

Many thanks,

Hello!

Hi,

I have to define a global variable in Pair_gran_hooke to be used in a compute source file. I have tried many ways but I did not succeed. How is that possible?

Thanks

Is there a possible way to know the number of contacts of each and every particle(may be with the wall or with the other atoms) and write the data(total number of contacts) into a new file?
I tried to follow this FORUM TOPIC but I couldnt figure it out : http://www.cfdem.com/forums/contactatom
It was printing only zeros for every ntimesteps.

Thank you.

Hi,

I have to detect the enduring contacts, so I have to apply criteria which identifies which one of the neighbors are in tight contact. I suppose I have to modify the source code but how is that possible ?

Thanks
Mohammad

Hi, All

I want to use the command 'fix move/mesh mesh linear/variable' to compress a sand pack.
What I've done is:
variable yl equal -0.5*v_dy
fix moveleft all move/mesh mesh left wall linear linear/variable 0. ${yl} 0.

I've also tried using v_yl instead of ${yl}.
However the error says: variable name 1 for fix move/mesh linear/variable does not exist.

Appreciate any help!!

Hi all,

Is that possible to allow a certain level of overlap between particles without generating interaction force? Suppose I have two particles with radius R1 and R2 positioned in a distance of d

Dear All,

I want to study the rheology of granular particles flowing on a inclined plane. Here, i want to apply periodic boundary condition (PBC) along length and width of the inclined plane. When i applied PBC for this system, it is taking the PBC for the simulation box (cube) not for the inclined plane. Can someone please help me how can i apply PBC on a inclined plane?

Many Thanks,

Narendra

Hi,

Iam trying to fill a container with particles. How can I fill the container upto a specific height.

Hi!
I'm doing a simulation of a cone crusher in LIGGGHTS of 480000 steps, the problem is that halfway through my pc rebooted unexpectedly. I want to ask if there is a way of restart the simulation, from let's say, step 100000 without having to start all over again. I would aprecciate any help

Kind Regards
