Fluid Particles overtop Inlet buffer zone
Hello everyone,
I am experienced this problem of fluid particles overtopping the inlet buffer zone.
My inlet conditions are:
<inout>
<memoryresize size0="2.0" size="4.0" comment="Initial memory resize (size0) and the following memory resizes according to initial inlet/outlet particles (default=2 and 4)" />
<determlimit value="1e+3" comment="Use 1e-3 for first_order or 1e+3 for zeroth_order (default=1e+3)" />
<inoutzone>
<refilling value="0" comment="Refilling mode. 0:Simple full, 1:Simple below zsurf, 2:Advanced for reverse flows (very slow) (default=1)" />
<inputtreatment value="2" comment="Treatment of fluid entering the zone. 0:No changes, 1:Convert fluid (necessary for outlet), 2:Remove fluid (recommended for inlet)" />
<layers value="8" comment="Number of inlet/outlet particle layers" />
<zone2d comment="Input zone for 2D simulations">
<particles mkfluid="1" direction="right" />
</zone2d>
<imposevelocity mode="0" comment="Imposed velocity 0:fixed value, 1:variable value, 2:Extrapolated value (default=0)">
<velocity v="0.08333" comment="Uniform velocity" units_comment="m/s" />
</imposevelocity>
<imposerhop mode="1" comment="Outlet rhop 0:Imposed fixed value, 1:Hydrostatic, 2:Extrapolated from ghost nodes (default=0)" />
<imposezsurf mode="2" comment="Inlet Z-surface 0:Imposed fixed value, 1:Imposed variable value, 2:Calculated from fluid domain (default=0)">
<zsurf value="0.21" comment="Characteristic inlet Z-surface (used for Hydrostatic option)" units_comment="m" />
</imposezsurf>
</inoutzone>
</inout>
Ant Initial conditions for the fluid is Vinitial=Vinlet.
Can someone help me with this issue ?

Dear user
First, check the XML examples in \examples\inletoutlet, which are closer to what you are planning to simulate.
Then, note that inlet initial creation is usually with a higher column of particles than the fluid domain.
In any case, @jmdalonso and @taffo may help here.
Dear Alex
Thank you for your response.
