Hi All,
First i wish all of you are fine and these bad days will past and you always be healthy,
I am asking if I can implement convective boundary conditions in 2.5D simulations for my cases, for now i am using Robin boundary conditions for my 2D cases but still have a problem in 2.5D cases.

any ideas for this outlet boundary conditions for my case 

I am using for 2D 
----------------------------
       <REGION REF="5">    <!-- Outlet  -->
<R VAR="u" USERDEFINEDTYPE="HOutflow" VALUE="0" PRIMCOEFF="D0/TimeStep" />
        <R VAR="v" USERDEFINEDTYPE="HOutflow" VALUE="0" PRIMCOEFF="D0/TimeStep" /> 
        <R VAR="p" USERDEFINEDTYPE="HOutflow" VALUE="0" PRIMCOEFF="1.0/(D0*Kinvis)" /> 
      </REGION>
--------------------

and for my 2.5D using
--------------------------------------------
       <REGION REF="5">    <!-- Outlet  -->
        <N VAR="u" USERDEFINEDTYPE="HOutflow" VALUE="0" />
        <N VAR="v" USERDEFINEDTYPE="HOutflow" VALUE="0" />
<N VAR="w" USERDEFINEDTYPE="HOutflow" VALUE="0" />
        <D VAR="p" USERDEFINEDTYPE="HOutflow" VALUE="0" />  
      </REGION>
---------------------------------------

is there any modifications in the new ver 5.0 regarding outlet boundary conditions?


Thanks,
Regards,
