multi-phase flow "Boundary particle was excluded"

Hi there,

I'm trying to use multi-phase flow v3.4 to simulate 'mud flow' on real-scale terrain, using an STL file. But the program kept giving me error message of "A boundary particle was excluded", see the '.out' file listed below:
------------------------------------------------

Using same method with DSPH v4.0, it worked well. But not with v3.4 multi-phase.
According to the previous discussion by @201270853 and @amir (http://dual.sphysics.org/vanilla/discussion/comment/1859/#Comment_1859), and FAQ#12, I tried to (a)modify the MK values; (b)extent the pointmin and pointmax; (c) drawpoint at both the pointmin and pointmax. But not working.

Could anyone please give me some tips on how to solve this problem?
Thanks so much.

  • Please, for doubts related with v3.4_LiquidSediment, email Dr Georgios Fourtakas:

  • Thanks Alex.
    I did have emailed Dr Fourtakas last week but still haven't got any response.
    So I came here to see if anyone can help or has the same problem.

  • Hi,

    This is a very special case and is not of benefit to other forum members, thus I have not commended on the forum page.

    Further, as you might imagine, we are very busy with other obligations, sometimes I forget to answer, so a follow up email after a few days or week is always good (to remind me of the question)!

    Thanks,
    George

    Sorry George. Just wanted to find out if anyone have the same problem.
    Didn't mean to rush you, and do understand that you guys are very busy. Respect your contributions to the code.

    Thanks for your email.

    All the best
