Re: [Yade-users] [Question #690942]: Concrete cube dimension, aggregate particle and peri3dController
Question #690942 on Yade changed: https://answers.launchpad.net/yade/+question/690942 Status: Answered => Open Faqih Maarif is still having a problem: Dear All First of all, permission, I say thank you for an enlightening answer, and I would like to apologize for not obeying the rules. Thank you also for the answers to the concrete cube's dimensions and the variation of aggregate particles. I will ask separately as a rule in the forum. My cases are the following: I have tested the compressive strength of the concrete cube (150mmx150mm), and I will be modeling in YADE. In modeling, I will consider stress and strain periodically. I am still confused about how to determine the (xxPath, yyPath,zzPath,zxPath,xyPath), as written below. xxPath=[(465,5e-4),(934,-5e-4),(1134,10e-4)], #old yyPath=[(2,4),(7,-2),(11,0),(14,4)], zzPath=[(5,-1e7),(10,0)], zxPath=[(4,2),(14,-1),(22,0),(28,2)], xyPath=[(1,1),(2,-1),(3,1),(4,-1),(5,1)], Can you please help?

Re: [Yade-users] [Question #690942]: Concrete cube dimension, aggregate particle and peri3dController
Question #690942 on Yade changed: https://answers.launchpad.net/yade/+question/690942 Jan Stránský proposed the following answer: Hello, > I am new to YADE welcome :-) > There are some of the questions ... next time please open separate "ask a question" for each question [1] > 1... > peri3dController > How to determine the dimensions of the concrete cube > there is an initial size = 1.2, but apparently, this is not the cube > dimension. there is no "cube", the simulation is periodic, simulating infinite space. To get dimension of a periodic cell (which is in no way related to physical dimensions - as it is infinite), you can use O.cell.size [2]. The initSize is passed to randomPeriPack. It creates a loose packing using makeCloud using the initSize size, then compress it. The parameter basically control number of particles in the simulation. Have a look at yade/examples/concrete [5] for simulation of "physical" samples. > 2. How to determine the variation of aggregate granules if specified; It is not possible "as is", randomPariPack [3] just supports uniform distribution (defined by radius and rRelFuzz parameters). To use defined particle size distribution, one option is to "rewrite" the randomPeriPack function [4] with adjusted makeCloud call. > in YADE Book (pg.280) it is better to use links to online documentation, like [6] > 3. How to determine the value (goal, xxPath, yyPath, zzPath, zxPath, xyPath), I'm confused with the determination of the numbers . I have read it in YADE Book (pg.280), but i dont understand about it. Please describe more what you do not understand. The path arguments are just a list of (time,value) pair, i.e. what value is prescribed at what time/iter. In certain cases, the values may be relative (e.g. the time on scale [0,1], internally rescaling the values with nSteps argument) The prescribed value is linearly interpolated between these defined points. Have a look at comments in the example you have posted and compare them with the simulation results. A note about modeling of concrete using periodic simulations: in case of strain localization, the periodicity has influence on cracks/strain localized area and therefore influence on overall response. Which is not a problem "by default", one just need to (should) have this in mind while using it. cheers Jan [1] https://www.yade-dem.org/wiki/Howtoask [2] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Cell.size [3] https://yade-dem.org/doc/yade.pack.html#yade.pack.randomPeriPack [4] https://gitlab.com/yade-dev/trunk/-/blob/master/py/pack/pack.py#L566 [5] https://gitlab.com/yade-dev/trunk/-/tree/master/examples/concrete [5] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Peri3dController.xxPath -- 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
