New question #665293 on Yade: https://answers.launchpad.net/yade/+question/665293
Hello everybody, I'm trying to add to my simulation the Law2_ScGeom_CapillaryPhys_Capillarity engine, but I am facing some problems with the tuning of some parameters. >From the wiki page about the capillary force model [1], I read about the set >of 10 files to be generated in order to make the engine work. When analysing >the given matlab scripts to generate them, I wasn't able to fully understand >one of the adjustable parameters, that is to say the so-called "rRatioVec". >Does it represent the ratio between the curvature radii? Is its lenght (i.e. >10, corresponding to the number of generated files) adjustable? Should I tune >the ratio values following my own simulation conditions? (e.g. considering my >own value of contact angle?) Moreover, I couldn't understand why in the given example of a YADE script implementing the capillary force [2], the capillary pressure is set to 10k through the following command: *** O.engines=[Law2_ScGeom_CapillaryPhys_Capillarity(capillaryPressure=10000)] *** Isn't the capillary pressure value discretized and changed through the Young-Laplace equation solution scripts? I can't understand the reason why it should be fixed, since during the liquid bridge strecthing its value should change, shouldn't it? I hope I made myself clear, thank you very much with any possible help!
