[Nek5000-users] Temperature gradient at a point

[nek5000-users at lists.mcs.anl.gov]

Hi Paul,

I am basically trying to solve a conjugate heat transfer problem in an
iterative manner, for flow over an infinitely long cylinder (2D).

I need to use the heat transfer at the boundary, to calculate the new
temperature at the boundary for the next time step. The
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.

Regards,
Pradeep
