JC,<br>
<br>
Are you doing this in serial or parallel?<br>
<br>
The main thing is to dump out the points at inflow, along with<br>
some type of discriminator so that you can subsequently<br>
associate function values (from your other code) with those<br>
points when you want to read them back in.<br>
<br>
In serial, this is easy - a bit trickier in parallel.<br>
<br>
Let me know which case is of interest and we can generate<br>
something for you.<br>

Hi Nek's,<br>
<br>
I have a question on how to impose inflow boundary conditions that are not<br>
analytical.<br>
I have for instance a Blasius velocity profile computed thanks to another<br>
code. I would like to impose this given profile as my inflow condition.<br>
At the moment I am using a polynomial expansion of the velocity profile in<br>
the userbc subroutine, however I would like to do things properly.<br>
<br>
I can interpolate the profile from my previous code onto the wall normal GLL<br>
discretization. That would give me a .dat file containing three arrays:<br>
first one is the y-discretization, second and third ones are the velocity<br>
(u,v) at these points. Question is how could I use these data to impose my<br>
blasius profile as inflow boundary condition?<br>
<br>
I assume it is rather straightforward, however I am not sure how and which<br>
indices should vary.<br>
<br>
Best regards,<br>
JC<br>
<br>
