Hi Paul,<br><br>I am basically trying to solve a conjugate heat transfer problem in an iterative manner, for flow over an infinitely long cylinder (2D). <br><br>I need to use the heat transfer at the boundary, to calculate the new temperature at the boundary for the next time step. The <br>
temperature for the next time step is solved for using this heat flux, by a function in the usr file using an FEM algorithm for the solid part (cylinder). The bc type I am using is Temperature - fortran function. <br><br>

Pradeep,<br>
<br>
if you give me some idea of the nature of your bc, I can<br>
perhaps help --- there are a large number of bc types already<br>
supported inside nek<br>

Hi,<br>
<br>
I wanted to know if there was a way to find the temperature gradient at a<br>
point. I need that information in the userbc function.<br>
<br>
I tried using gradm1(), but I am not sure how to get the value at a given<br>
point.<br>
<br>
Thanks,<br>
Pradeep<br>
