inlet/outlet + moving walls + periodicity
Hi everyone,
I've modified the example 07_CurrentHull to include moving walls + periodicity in the computations. The fluid flow is set to 1.71unit/s-1 in the X direction.
- Walls are defined as following :
<setmkbound mk="0" />
<drawbox>
<boxfill>bottom | front | back</boxfill>
<point x="-2" y="-1.0" z="0" />
<size x="5" y="2" z="0.4" />
</drawbox>
- Movement is defined as following :
<motion>
<objreal ref="0">
<begin mov="1" start="0" finish="100" />
<mvrect id="1" duration="100">
<velini x="1.71" y="0" z="0" units_comment="m/s" />
<vel x="1.71" y="0" z="0" units_comment="m/s" />
</mvrect>
</objreal>
</motion>
- Periodicity is defined as following :
<parameter key="XPeriodicIncZ" value="0" comment="Increase of Z with periodic BC in axis X" units_comment="metres (m)" />
Boundaries and surface are exported in VTK. Outputs are displayed in blender. Here is the initial set (Hull_0000, Box_0000, Surface_0000) :
Here are the the steps (Hull_0001, Box_0001, Surface_0001) and (Hull_0010, Box_0010, Surface_0010) :
Although the Xperiodicity seems to be correct, the orientation of the box do not match its initial presets. What am I doing wrong ?
Thanks in advance for your kind help. Cheers,

Hi everyone,
doing some test to understand where the issue could be, I find that :
It does not seem possible to perform 3d calculations with inlet/outlet and walls moving with the flow, isn't it ?
Any clues ? Cheers,
