Hi,

I define a wall with the stl style, and I want to change the normal direction of this wall. Can anyone tell me how to do it ?

Thanks

I have the Ubuntu makefile for Opensuse 12.3 but the cluster system is on Suse 11. Can anyone please provide me the working makefile for Suse 11

Dear all,

i'm fairly new to LIGGGHTS and i'm simulating particles flowing trough a pipe with periodic boundary conditions in flow direction. I would like to count the particles per iteration which are passing my periodic boundary. I'm able to do so by dumping particle positions to a file and check the passing by a script.
I was wondering if there is a way to do so using LIGGGHTS?

Best regards
Felix V.

Hello everybody,

I'm writing you because I can not run a script with the fix pour/legacy. I do not understand what is wrong with my input file. After running the command liggghts

I already have Openfoam installed with thirdparty. I have openfoam 2.2.0 and 2.2.x installed.

My question is How do I install LIGGGHTS and then use it for coupled examples.

Hi,
I want to insert particles into a hollow cylinder. Can anyone tell me how to achieve this?
Thanks

I'm trying to simulate a particle size distribution. Using the attached file (with 8 cpus) leads to the wrong amount of overall mass (0.445609 instead of 0.360).

At first the number of 6755 particles (mass 0.359951) is calculated, which is ok. But then only 3904 particle templates (mass 0.293721) can be inserted at step 1. This leads to "WARNING: Particle insertion: Less insertions than requested (fix_insert.cpp:622)". Later on: "inserted 2851 particle templates (mass 0.151888) at step 33334 - a total of 6755 particle templates (mass 0.445609) inserted so far."

Greetings friends,

I was wondering if it's possible to simulate the effect of jamming (blockage) in a screw conveyor due to non-compatible particle size distributions, too high feeding rate, too high friction among particles, etc...

Specifically, do the particles interact with the rotating impeller and can influence its rotation speed ? Or cause the rotational operation to stop ?

Hi LIGGGHTS users,

I am fairly new to LIGGGHTS and modelling a rather simple problem.

What I am basically trying to do, is to fill the rectangular hopper of a screw conveyor, release a stopper (z-plane primitive) and finally start the screw conveyor.

My problem seems to be related to the fix pour/legacy. The same script, as attached to this post, worked when I used fix insert/pack.

Hej guys.

I'm trying to creat a mesh but instead i get this ERROR:
