Wang Yu is still having a problem:
Hi, Manfred
I'm sorry I didn't express clearly.
I was using Ubuntu 18.04 in the past, I guessed whether kdevelop would
adapt better in the old version, so I used the 16.04. But as you said, I
just installed Kdevelop 5.5.0 in Ubuntu 20.04 with the 'sudo apt-get
install kdevelop' command. When I try to import the yade-trunk project,
I still get error：
in the GUI-
Failed to configure project 'trunk' (error message: Configuration failed.). As
a result, KDevelop's code understanding will likely be broken.
To fix this issue, please ensure that the project's CMakeLists.txt files
are correct, and KDevelop is configured to use the correct CMake version
and settings. Then right-click the project item in the projects tool
view and click 'Reload'.

[Yade-users] [Question #703319]: How to get Kdevelop to work properly
New question #703319 on Yade: https://answers.launchpad.net/yade/+question/703319 Hello, As mentioned in my previous question, I am going to use Kdevelop to write and debug my own constitutive model. In fact I already have an understanding of the basic framework of yade, but the Kdevelop I installed according to the tutorial does not work properly. I've been using yade in Ubuntu 18.06 for the past two years. Whether I follow the ‘’sudo apt-get install kdevelop” command or directly download the packaged kdevelop.AppImage file on the official website, errors will occur. The code in the project I imported cannot find the existing library, and the terminal reports errors of "failed to parse translation unit" (although kdevelop will report a lot of errors, but I guess many can be ignored). I tried a lot but couldn't solve it, so I guess it might be a version or dependency library issue. I installed ubuntu16.04 in vmware, and executed ''sudo apt-get install kdevelop' and things seemed to get better. The code can find its library, but the classes in some code files don't seem to be defined correctly (the code is absolutely correct, but Kdevelop doesn't seem to treat it as a class), so that their mutual references are still unrecognized. Eventually I still want to be able to debug yade in Ubuntu 18.06. Can someone explain why? Do I have to install Kdevelop from source for it to work?

New question #692106 on Yade: https://answers.launchpad.net/yade/+question/692106 Hello! I use "export.VTKExporter.exportInteractions(what=dict(forceN='i.phys.normalForce.norm()'))" to export force chain and "VTKRecorder" to export spheres' information like positions. But I found that the force chain and the particles do not match perfectly when I observed them in paraview. In detail, some of the force chain seems to fly out of the periodic cell. For example, particles positions on the left/up side of the cell show no force chain(there should have been). On the right/down side of the cell, the force chain(should appear on the left/up) appear out of the cell. I don't know if I made myself clear. I guess the problem can be solved by using "cell.wrap" properly but I don't know how. Looking forward to your help.

Wang Yu proposed the following answer:
Hello,
In my recent simulation I used
ymport.textExt('xxx.txt',format='x_y_z_r_attrs',attrs=attrs) to import
particles information successfully. To do that, your 'file.txt' should follow
the format(x_y_z_r_attrs).
For more detailed information you can read the 'ymport' section of the
documentation.
I hope that helps.

My domain of simulation is 3D. I found that the multiprocessing pool work successful when my RVE packing is small enough, but when I use an RVE of more than 1000 particles(mean radius=0.005), the error code will appear (BrokenPipeError: [Errno 32] Broken pipe)and the simulation would stop. With my poor understanding of multiprocessing library, I guess this is probably due to too many particles leading to too much data. In addition, I use cohesive particle model in RVEpacking.

Maybe I have some misunderstanding with O.interactions.erase. If deleting existing interaction has no particular effect on future interactions,so what's the purpose of this function? I found that partcles within an agglomerate are bonded tightly (their interaction may have some "cohesive" property). If the new interactions(partcles between different agglomerates) are created according to the same functors(Ig2, Ip2 and Law2 for CpmMat spheres), why aren't there the same cohesive properties (there are no bond between partcles from two agglomerates)? According to my guess(may be wrong),O.interactions.erase break the interaction for a moment, and the bond part of interaction (like cohesive) can not be rebuilt because of the special property of CpmMat. Am I right? In fact, I want to creat some agglomerates: A-type-interaction between partcles within an agglomerate is different from B-type-interaction between agglomerates. Is there any example or advise for my question? PS:With my current ideas,I think out of two approaches: 1. A-type-interaction and B-type-interaction use the same Ip2 and Law2 functors but with different arguments(about stiffness or cohesive property) 2. Two types of interactions use different Ip2 and Law2 functors. Do these approaches accessible in Yade?

Re: [Yade-users] [Question #690742]: How does the interaction.erase function work in the agglomerate examples?
Question #690742 on Yade changed: https://answers.launchpad.net/yade/+question/690742 Status: Answered => Open Wang Yu is still having a problem: Thanks a lot Jan! Maybe I have some misunderstanding with O.interactions.erase. If deleting existing interaction has no particular effect on future interactions,so what's the purpose of this function? I found that partcles within an agglomerate are bonded tightly (their interaction may have some "cohesive" property). If the new interactions(partcles between different agglomerates) are created according to the same functors(Ig2, Ip2 and Law2 for CpmMat spheres), why aren't there the same cohesive properties (there are no bond between partcles from two agglomerates)? According to my guess(may be wrong),O.interactions.erase break the interaction for a moment, and the bond part of interaction (like cohesive) can not be rebuilt because of the special property of CpmMat.

[Yade-users] [Question #690742]: How does the interaction.erase function work in the agglomerate examples?
New question #690742 on Yade: https://answers.launchpad.net/yade/+question/690742 Hello everyone, I am new to Yade. I have run the script simulation.py in agglomerate examples in the trunk version https://github.com/yade/trunk/tree/master/examples/agglomerate It use O.interactions.erase(i.id1,i.id2) (line 52) to delete specified interactions that has been created using Ip2_CpmMat_CpmMat_CpmPhys(cohesiveThresholdIter=1) IPhys and Law2_ScGeom_CpmPhys_Cpm() Lawfunctor. So,what IPhys and Law would be used in these pairs of partcles in the following simulation by default or any manual definition when they are deleted already? I have found that there really exist interaction between a pair of bodies (their interaction have been deleted before),but I don't understand how to define the interaction attribute -- 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
