Re: [Yade-users] [Question #586294]: Uniform Traction Boundary
Question #586294 on Yade changed: https://answers.launchpad.net/yade/+question/586294 Bruno Chareyre posted a new comment: Hi, 1) and 2) can work if you have only very small deformations. If the deformations are larger, the "boundary" particles you find in the initial state may not be at the boundary all along the simulation, they will be replaced by others which will soon be ejected from the problem if they don't get the "boundary force" they should. A clean solution is to have an updated mesh of the contour (a concave hull) and to update the forces on the boundary particles continuously. It is not implemented as is but algorithmic blocks which can be used to get concave hull are present in the code.

Re: [Yade-users] [Question #580450]: Applying differents force values
Question #580450 on Yade changed: https://answers.launchpad.net/yade/+question/580450 Status: Open => Answered Jan Stránský proposed the following answer: Hi Felipe, thanks for the complete scripts. I have tried them and did not find anything wrong. Just to summarize: > I have found divergences when i have apply the force on the surface and then > I read the value that i recorded. > When I read the force, I noticed that the applied values were different from > 200. it is simply because read force and applied force are intrinsically different values, see my previous comments (you don't read the applied (=prescribed) force, you read total force applied on the body (=prescribed force+forces from interactions) > is it the correct way to apply the force on the surface? How can i be sure that i really applied the force value on the surface? yes, it is the correct way. You can be sure because you used the command :-) You can also use O.forces.permF(someId) to check if a perment force is set on body with id=someId (you can use this command to get prescribed force and save it, maybe this is what you wanted from the ForceRecorder?). cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

Re: [Yade-users] [Question #586294]: Uniform Traction Boundary
Question #586294 on Yade changed: https://answers.launchpad.net/yade/+question/586294 Gary Pekmezi posted a new comment: Thank you for your suggestion Bruno. I currently need to run small deformation simulations, however I may need to simulate larger deformations in later and either way the "concave hull" approach seems like it would be more robust. So I'd like to inquire about the "algorithmic blocks" you reference. My initial idea for the hull is as follows. Perhaps I periodically call TesselationWrapper to mesh the domain then traverse the exterior of it to find the boundary. Then I suppose I can apply a force directly on the particle. By the way, I am not familiar with ServoPIDController, might it be a better way to apply force on the boundary particles than setPermF?

[Yade-users] [Question #590359]: Error running with Capillary Example
New question #590359 on Yade: https://answers.launchpad.net/yade/+question/590359 Hi all, Good to return to Yade after two years. I'm running Linux Mint 17 64bit I'm trying to reuse the Capillary Test Example given here: https://yade-dem.org/wiki/CapillaryTriaxialTest https://github.com/yade/trunk/tree/master/examples/capillaryLaplaceYoung I installed Yade by: sudo apt-get install yade, the version turns out to be 1.07 The problem I got is I cannot start the test from the example code mentioned above.

Question #590359 on Yade changed: https://answers.launchpad.net/yade/+question/590359 Status: Open => Answered Jérôme Duriez proposed the following answer: Re-hi Hien, and welcome back to YADE, I still do not know which python script (from examples/capillaryLaplaceYoung folder) you tried ;-) but Yade 1.07 seems to me way too old to work with the current capillary files. To be sure, ask for "CapillaryPhys().dict()" (I hope to avoid any typo here, as I'm currently on Windows) in your YADE terminal to check all possible attributes of this class in your version. If "nn11" [*] is not present, it confirms your Yade version is too old (or your capillary files too recent) for things to work. (To be precise, your capillary C++ code is probably unable to deal with the recently added data in capillary files, such as this nn11) Jerome [*] https://yade- dem.org/doc/yade.wrapper.html#yade.wrapper.CapillaryPhys.nn11 -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

Hien Nguyen is still having a problem:
Thanks Jérôme,
You're right I think.
Here is the output of CapillaryPhys().dict()
{'Delta1': 0.0,
'Delta2': 0.0,
'capillaryPressure': 0.0,
'fCap': Vector3(0,0,0),
'fusionNumber': 0,
'isBroken': False,

'ks': 0.0,
'meniscus': False,
'normalForce': Vector3(0,0,0),
'shearForce': Vector3(0,0,0),
'tangensOfFrictionAngle': nan,
'vMeniscus': 0.0}
The script I used in the example folder is CapillaryPhys-example.py,
appology for not mentioned it before.
So what version you advise me to use? I'll consider the compile version
of YADE.
