simulatuin the asphat with Burger's contact Model

Hello,

It is always good to attach a link to the model if you know some.
Fortunately google is clever enough :-)
I am afraid this type of visco-elastic model is not yet available in Yade,
so if you want to use it in Yade, you will have to implement it.

For what type of loading do you want to use it? If the purpose is long-term
creep effects, I am not sure if explicit DEM is the right way to do it..

good luck
Jan

Hallo Jan and all,
i have funded the the Dissertation of Mr. Dr. Jinsong Chen from Uni tennessee. He has made the Burger contactmodell with Yade. But i don't konw. how can i compile the C++ Code. Can you oder anyone explain me how can i do it?

thanks
xin

Hi,

first read https://yade-dem.org/doc/installation.html.
what operation system do you use?

If you want just use Yade, you don't need to compile it, you can use
precomplied version. However, if you are going to implement something
yourself, yo can't avoid the compilation and in that case I would prefere
"downloading" the source with git and then use "cmake", "make", and "make
install" commands.

As Yade is open source, anybody can download it and modify. But there is no
obligation to public these changes. You can contact directly Dr. Chen and
ask how he did it and if he can provide you some files. It is also possible
that he commited the changes to Yade and I only could not find it in the
documentation - I was not searching in detail..

cheers
Jan

There are some files from Dr. Chen [1], but, it seems, the Yade
version is pretty old there.

Hallo Jan, Hallo Anton,
I will make a Presentation by Company Bomag on Monday for the Simulation with DEm for the road roller. For this reason i will use the Burger's Model.
I have read the Dissertation und saw the Code. But how can i use the Code? Shall i use gcc oder cmike and compile the entire Code of th Yade oder only the new code. I have lerned C++ but i have no experince of Compilation in Linux.
Thank you very much
regards
Xin

Hallo Jan, Hallo Anton,
You can get the dissertation and another in the link http://trace.tennessee.edu/utk_graddiss/index.2.html oder http://trace.tennessee.edu/utk_graddiss/

Xin

If that contact model is the same, which is described
for PFC [1], I believe it is not really difficult to implement.

Hallo Anton ,Jan,
Thanks. Can i modify the code dirct in Yade what i install in my labtop and without compilation?
regards

Well, you can of course directly modify the code. But if you want to make
the new changes work, you have to compile the code.

But it should be no problem. Even if you have no experience, we can lead
you step by step :-) at least in the case you work on linux.

Cheers
