inletOutlet particle resolution

circlescircles
edited February 2019 in DualSPHysics_v4.3_Beta
Hello,
I'm playing with examples/inletoutlet/1_FlowCylinder and when I increase the particle spacing I get the following error



If I keep the dp the same but increase the number of in/out layers, I get the following error



But, I get no errors if I use extapolated velocity(mode=2) and choose hydrostatic option for the density( mode=1).

    Have you tried using the fixed domain command and slightly increase the domain in each side? It has helped for me earlier.

    Kind regards

    I've played with inlet-oulet as well, It definitely is a case of particle outside of domain (as stated in the error), you should mak sure that the buffer of the inlet is inside the domain after gencase. try this : https://dual.sphysics.org/index.php/faq/#Q_12

    So, on a x-z plane with x pointing right, the buffer layer particles are created in -x direction.

    @Asalih3d Is the fixed domain same as useboxlimit?

  • circlescircles
    Using the given dimensions in CaseFlowCylinder creates the following domain




    But, when I change the dimensions and create a smaller domain, I only get the buffer layers.




    Does the command "void" create a reserved space for fluid particles which is void? If this is the case, how am I getting an area filled with particles when I use the given dimensions? Or am I missing something?

    Thank you so much.

    I think you got fillbox wrong.

    check the xml guide please !
    You just defined a box starting at x=0, with size of 0.3 ! and you want it to be filled starting from the point at x=1... this point is outside your box ! so no particle are created.

    Also, I'll avoid having the fillpoint on the domain limit (first lign of the fillbox)
    so change x="1" to x="0.9"

    "void" does not reserve space ! it just a way of telling the program "Put particles in this box starting from this point, as long as the space is void (no particle already in it).

    Good day

    Oh, for some reason I did not think it was the filling algorithm and I thought x=1 specifies the direction.
    It works now thank you.

    Have a good day!
