Re: [Yade-users] [Question #707788]: Porosity in rotated measuring area
Question #707788 on Yade changed: https://answers.launchpad.net/yade/+question/707788 Paul Schröder posted a new comment: Hi Karol, Changing the position of the particles and facets relative to the analysis volume is an interesting approach. Since I stop the movements in the simulation space to evaluate the current state anyway, the whole thing should be possible with a simulation that continues afterwards. However, I used the following solution for myself: The analysis cell for porosity detuning is moved to different positions and kept parallel to the coordinate axes. The particles and facets do not need to be moved. In the areas where the porosity measurement space is partially outside my test space, I then correct the calculated porosity with a factor. This correction factor is made up of the total measuring volume of the "voxelPorosity()" function and the test volume in that area. Since there are no particles in the remaining area, I can only calculate the porosity for the examined space. Your help was another inspiration for me, thank you very much!

Question #707788 on Yade changed: https://answers.launchpad.net/yade/+question/707788 Status: Open => Needs information Karol Brzezinski requested more information: Hi Paul, Do you need to measure the porosity on the fly (required to trigger some actions in the simulation)? If it can be done in postprocessing, the simplest way would be using axis aligned porosity function and rotating the sample.

[Yade-users] [Question #707788]: Porosity in rotated measuring area
New question #707788 on Yade: https://answers.launchpad.net/yade/+question/707788 Hello dear YADE community, I would like to determine the porosity locally in a delimited area in the experimental space on which my simulation is based. In principle, the command "voxelPorosity()" seems to be well suited for this purpose [1]. The application of the command itself works quite well. If I have understood the command correctly, the area to be analyzed with the given vertices is spanned by a cuboid, parallel to the coordinate axes [2]. However, I am afraid that my further requirements can thus not be completely fulfilled: I want to sample a cylindrical experimental space locally with respect to porosity. This means for the porosity determination that I want to rotate this cuboid or here specifically as a cube around the z-coordinate. For this rotation I can for example specify a quaternion with, which the "voxelPorosity()".however does not pick up. How can I determine the porosity of a cube (filled with spherers) rotated around the z-axis? I am looking forward to help and hope to find a solution to the problem, with best wishes, Paul [1] https://answers.launchpad.net/yade/+question/690057 [2] https://answers.launchpad.net/yade/+question/384899 -- 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
