Hi Timo,
<div><br>
</div>
<div>For this particular experiment we would like to prescribe the x-component of velocity for the
<i>vertical</i> boundaries with a function, but not fix the y-component. In general, being able to separately set the velocity component boundary conditions on all boundaries would indeed be useful.</div>
<div><br>
</div>
<div>Thank you,</div>
<div><br>

<br>
Yes, right now you list a given indicator as zero, tangential,<br>
prescribed, or not at all and this logic applies to all components. We<br>
can change this, though.<br>
<br>
To make sure I understand you correctly: you want for the bottom to<br>
prescribe the x-component of the velocity to a certain value (given by<br>
a function), but not fix the y-component? What about the other<br>
boundaries?<br>
