Announcement for an discrete element code for foam

stephan · February 16, 2007, 08:53

hi all,

in two or three weeks i will set a link for a dem-code based on liblagrangian ( i have to clean up the code first).
the code uses the spring-damper-model from tsuji and will therefore be easy to extend to other collisionmodels.
it allows collsions between more than two particles at the same time and uses a cell-linking algorithm to achieve better perfomance. it could be interesting for people doing mol. dynamics or dense particle-flows.
anybody interested?

Hi Stephan,
This sounds interesting! I have done a bit of DEM-simulations using OpenFOAM. I would be happy to see how you have implemented the algorithm and perhaps share some experience I gained in my project.

i would be very interested in working with this. i look forward to your release ...

hi,

since i have almost no time rightnow it will take some weeks more - but here 3 pics from a simulation (kuipers, jie li " Gas-particle interactions in dense gas-fluidized beds" -2003)
first the situation just after the start and two pics after some seconds.
(gas flows come from the whole base plate)

the point on these pics is that there is no overlapping.

any luck with this? still very interested.

stephan · June 29, 2007, 08:51

hi,

sorry that the source still isnt there - i am still havent clean up the source -about 60% of the works is done. the source will be online in two weeks - i promise

!
i am just pretty busy - i started my pdh and was busy finding somebody how wants to pay for this phd-project....

greetings

hi,

i made it finally to pack a version of my DEM application.
If anybody wants a copy, write me an email and i will send you a copy.

greetings

Dear Stephan,

I am interested. Could you please send me a copy? Thanks!

hi,

in case some of the foamers which got the source from the dem are actually using the code:
you should double the depth of the bed in blockMeshDict from 0.002 to 0.004 (the size of the particles) and higher the inlet velocity a bit.
sorry for the messed up case-dir..

hi,

i hope everybody who wanted the sources got them. if not just write an email.

Stephan, could you send me a copy of sources ?

Best regards,

hi,

i had some trouble writing a mail to Sreekanth Pannala - no matter if i attach something or not the mail comes back with an failure notice, which includes the information that the mail couldnt be delivered.

greetings

hi there,

Could you send me a copy? I emailed you a bit ago but perhaps I got the wrong address. My email is abcosta@purdue.edu

Thanks

Hi, Stephan,

I still have not gotten the code yet. Could you please send it again? Thanks!

hi,

after sending sources to about 20 people i guess that it will be much more efficient to put it on the wiki....

since i am quite busy right now this will happen in the end of september.

greetings

is your code coupled? how did you implement it?
