Ran bingle.py of tutorial and found error

Asked by Celso Neto

I downloaded the ESyS Particle Live CD to test, learn and try simulate bulk material transport in conventional belt conveyors. First I would like your opnion about the use of ESyS to this simulation, It's possible?
Too, I want to know if its possible simulate material with shape not spherical, but cilindrical.
In my first test of ESyS, learning use the software (yesterday), I had dificulties, I copied the programation of Apendix 1 (A1) of Tutorial (bingle.py) and tried run but I found the message below:

guest@guest:~$ mpiexec -machinefile hosts.txt -np 2 mpipython bingle.py
The program 'mpiexec' can be found in the following packages:
* lam-runtime
* openmpi-bin
Try: sudo apt-get install <selected package>
bash: mpiexec: command not found

What is this error, Can you help-me?

Hi Celso,

Thanks for your questions and welcome to ESyS-Particle!

To my knowledge no-one has yet used ESyS-Particle to simulate belt conveyor systems. That doesn't mean ESyS-Particle cannot be used for that though. Please see this FAQ for more information:

Currently ESyS-Particle only supports spherical particles in 3D simulations and cylindrical disks in 2D simulations. There are no plans to support other particle shapes in 3D as yet. Most experienced users of ESyS-Particle find that clustering spherical particles together to form other shapes is a good alternative. Often using clusters has more advantages than disadvantages e.g. clusters can be calibrated to fracture or fragment if your application requires that. An example simulation using cylindrical clusters can be seen here:

Regarding your specific problem with the ESyS-Particle Live CD, try the following command instead of the "mpiexec" command:

mpirun -np 2 /usr/local/bin/mpipython bingle.py

If you still experience problems with the Live CD, please let me know. The Live CD is quite experimental so problems using it should be expected.

If your distribution Ubuntu Here you will find wandering

Thanks Rashed for the information. The link you provided is for a mirror of the ESyS-Particle Live DVD I put together about two years ago.

For Celso and others, there are two more recent versions of the ESyS-Particle Live DVD available for download.

The first version is based on Xubuntu-9.04 for 64 bit PCs and available here:

The second version is based on Linux Mint for 32 bit PCs available here:

The second version has a slightly more recent version of ESyS-Particle pre-installed. Some of the tutorials may require modifications to work with this newer version.
