Filling STL file using fill box

Shadi

Dear DualSPHysics users,

I am working on a case of sliding a fluid along a boundary. The fluid is imported as a STL file, and to fill it with particles I have used fill box. However, the STL file can not be entirely filled with particles

The cross section shows that the STl file is like a boundary. I would greatly appreciate your insights on how to resolve this issue.

Here is a part of XML file:

 <geometry>

      <definition dp="5">

        <pointmin x="-5000" y="-5000" z="400" />

        <pointmax x="5000" y="3500" z="2500" />

      </definition>

      <commands>

<mainlist>

<setshapemode>actual | dp | bound</setshapemode>

          <setdrawmode mode="full" />

                   <setmkbound mk="0" />

<drawfilestl file="GROUND_DOWNSTREAM.stl"/>

<shapeout file="Boundary" reset="true"/>

      

   <!-- Fluid-->   

           

           <setmkfluid mk="1" />

<setdrawmode mode="full"/>

<drawfilestl file="DRIR.stl">

 <drawmove x="-5" y="0.0" z="20"/>

</drawfilestl>

<fillbox x="2255" y="-5" z="920">

<modefill>void</modefill>

<point x="1600" y="-1100" z="620"/>

<size x="2000" y="1800" z="980"/>

</fillbox>

<matrixreset/>

<shapeout file="Debris" reset="true"/>  

                        

</mainlist>

          

      </commands>

    </geometry>

  </casedef>

  <execution>

Best regards,

Hello,

You should verify if the fillbox seed targtes a empty space inside your DRIR.stl

Thank you very much TPouzol,

I double checked it and the point is an empty space inside the STL. Upon closer inspection, I can see some part of STL file remain unfilled. I used setdrawmode = face and then filled it . Despite these , there is still empty space inside.

           <setmkfluid mk="1" />

<setdrawmode mode="full"/>

<drawfilestl file="DRIR.stl">

  <drawmove x="-5" y="0.0" z="15"/>

</drawfilestl>

<fillbox x="2400" y="-370" z="1042">

<modefill>void</modefill>

<point x="1700" y="-1000" z="720"/>

<size x="1800" y="1600" z="880"/>

</fillbox>

<matrixreset/>

<shapeout file="Debris" reset="true"/>  

I would appreciate any insights or suggestions .

Best,

Shadi
