Cannot draw solid fluid with drawprism

qwerty987

Hi DualSPHysics,
I try to make fluid with drawprism. Turned out, with setdrawmode mode=full, gencase only make the face without the solid. Then i changed setdrawmode mode="solid", it said "no points drawn". I suspect it is due to my choice of point for prism.

Can someone take a look at my def.xml code here please? : https://drive.google.com/file/d/0B8Vv_GZzZv9Fd3lHZmtzX3FVOHc/view

Thank you for your help.

You are not creating the PRISM correctly:

SOLUTIONS:
1) you have to define your points in the inverse order
OR
2) you can specify first the points at y=18.2 and then y=0 with the same order you have now

However the best option is always creating the boundary and then using fillbox to fill with fluid... if this is what you were trying to do, not sure.

Hi Alex, your (1) solution actually works! thank you very much for your help. Just one another question, are there some rules we have to follow in points ordering to make a solid prism with drawprism?
because sometimes it works and another time it doesn't.

Thanks and regards.

Is it correct for floating object : ?
setdrawmode mode="full" />
setmkbound mk="51" />
drawprism mask="0">
point x=" 0" y=" 0" z="1.4" />
point x=" 0.25" y=" 0" z="1.5443" />
point x="-0.25" y=" 0" z="1.5443" />
point x=" 0" y="10" z="1.4" />
point x=" 0.25" y="10" z="1.5443" />
point x="-0.25" y="10" z="1.5443" />
/drawprism>
shapeout file="Wedge" reset="true" />

this prism havent particles inside

Alex

you should create the particles in clockwise rotation!

Dear Alex,
Thank you,
but
where it should be?
page 27 XML_GUIDE_v4
draws a triangle with tree points (points must always go counterclockwise)
page 33
drawprism>: draws a prism with a minimum of 6 points
and nothing about counterclockwise or clockwise

and furthermore I performed search and dont find any other pages with
only page 27

Hi Alex,
could you help me again with these:
drawprism>
point x="1.5" y="18.2" z="-0.72956" />
point x="3" y="18.2" z="-0.42956" />
point x="15" y="18.2" z="0.00163" />
point x="15" y="18.2" z="-0.29837" />
point x="3" y="18.2" z="-0.772956" />
point x="1.5" y="18.2" z="-1.02956" />

point x="1.5" y="0" z="-0.72956" />
point x="3" y="0" z="-0.42956" />
point x="15" y="0" z="0.00163" />
point x="15" y="0" z="-0.29837" />
point x="3" y="0" z="-0.772956" />
point x="1.5" y="0" z="-1.02956" />
/drawprism>

i still couldnt figure out how the points ordering works (clockwise or counterclockwise). Thank you.

Alex

Points: clockwise (we always start with the xmax,zmax)
And first points with ymin and then points with ymax
